A DNS Failover Service – Is it right for you?

Over the years, DNS Failover has become a very popular service primarily due to the fact that it is relatively inexpensive and fairly easy to deploy and manage. But is it the right solution for your organization? In this article, we’ll outline what DNS failover is and provide an overview of the benefits and appropriate uses for this type of technology.

What is DNS Failover?

First, we must define what DNS failover is before trying to understand whether or not it offers benefits. Simply put, DNS failover is an add-on feature of a DNS Service and is a system that consists of two main components. The first component monitors servers or devices behind IP addresses in an effort to determine their state, e.g. up or down. Second, it uses the server state information to automatically update the IP address associated with a particular DNS record, such as an ‘A’ record, ‘AAAA’ record or otherwise. It may consist of other components designed to deliver email or SMS alerts in the event that an outage is detected or changes are made, but any successful DNS Failover solution must consist of at least the first two essential elements.

Common Applications for DNS Failover

So now that we know what DNS Failover is, what is the most common use for it and what applications can benefit from this method of automating DNS updates?

Perhaps the most obvious use that comes to mind is to control web traffic. Failing over between redundant web servers is a very common implementation, and is probably the most frequently used application. From the failover system’s perspective, it really doesn’t matter where the two IP addresses are, so long as they are different. So because of this, it could be used to failover between two different servers at the same datacenter, servers at different datacenters (even across the globe) or it could be even the same server with two different network connections, each having their own IP address, for example a server at a corporate office with one IP on each of two different T1 lines.

Naturally, what can be done for web servers can also be done for mail servers, FTP servers, streaming media servers or VoIP servers, just to name a few. Essentially, if it has an IP address and can be monitored externally, DNS Failover can route traffic to it when it is up, and redirect to another server when it is down.

Common Features

Most well thought out DNS Failover implementations should have at least a few basic features. First, and probably paramount to failover success, is monitoring. The more advanced the monitoring feature-set, the better. This allows you to detect outages as accurately as possible. At a minimum, we would expect functionality to fine-tune the monitors and to run them from multiple geographic locations in order to create an accurate picture for when failover actually needs to occur. Of course, it should probably go without saying that the monitoring and alerting functionality should be able to send alerts via email, SMS or both.

Another important feature, in our opinion, is some flexibility in how traffic is routed. The most common traffic routing configurations are sequential or round-robin. Sequential allows you to list servers in the order you want traffic to be delivered so that if the server with a priority of 1 goes down, it sends traffic to the server with a priority of 2 and so forth. Round-robin publishes a DNS record for every one of the active and available servers so that traffic is distributed amongst them as evenly as possible. When one goes down or becomes otherwise unavailable, it is simply removed from the pool allowing traffic to continue being distributed amongst the remaining server(s).

And finally, you’ll probably want a feature that prevents the automatic re-announcement of a server’s IP address when it comes back online. In the case of a server providing static web content, re-adding may not pose a problem, but in the case of a database server requiring resynchronization, this little feature is critical.

Limitations of DNS Failover

The biggest limitation when using DNS Failover for application switching is the ability to quickly detect an outage and make a change that will actually propagate the Internet in relatively short order to seamlessly redirect users, both current and future. Even the best DNS Failover solutions that accurately detect an outage and update DNS quickly and accurately still leave customers at the mercy of a well known problem called caching. This is an extremely tough issue to resolve because it is not within the DNS Failover service providers control.

Caching issues are created when ISPs ignore TTL values, or they can be caused by something as simple as default Internet browser settings which are configured to cache images in order to improve page load times. The shortest compliant TTL value is 60 seconds, and for some ISPs this is simply too short. AOL, for example, is known to ignore low TTL values and substitute them with something much higher, say 15 minutes, for example. But other than those ISPs who ignore TTL values, a 60 second setting in theory *should* propagate the Internet relatively quickly.

Is there anything better?

Depending on your application, Cloud Load Balancing might be a better fit. That, of course, should be dictated by your specific requirements for uptime, flexibility for balancing traffic among servers and how critical the need to avoid caching created by TTL avoidance or just plain old browser settings. Cloud Load Balancing is similar in design, but offers extremely powerful traffic management solutions similar to hardware load balancers (except on a global scale) for serious online organizations.

Bringing Superfast Broadband to the UK’s Cities

The Super Connected Cities scheme is a unique opportunity for small to medium sized companies in cities up and down the UK to bolster their business online.

Some areas of the UK have faster broadband than others, and the scheme, which is funded by the Department of Media, Culture, and Sport, wants to create a level playing field for the entire country and help businesses compete internationally through high speed communications.

Under its broadband investment policy, the government is aiming for 95% of the country to be receiving broadband speeds of at least 24 megabits per second (Mbps) by 2017. The program is advancing rapidly. The standards for broadband speed are constantly growing and UK businesses cannot afford to be left behind.

More than £150m has been invested in the Super Connected Cities program thus far. This doesn’t just includes powering local SMBs with superfast broadband but also installing comprehensive public Wi-Fi spots throughout cities on public buildings in city centres.

Through superfast broadband vouchers, and the nationwide scheme to distribute them, SMBs can get the leg up they need to get connected and to ensure they’re well placed to do business both nationally and internationally. Please note that vouchers are of limited supply, and the government has indicated that the scheme is reaching it’s funding limit.  Businesses can apply for fast tracked, pre-approved packages at Superfast Vouchers.

Since launching in April of this year, several cities have already benefited from the scheme and more cities are slated to join the program in the future, giving more SMBs an opportunity to improve their online performance, provided they meet the criteria.

Dozens of cities and towns up and down the UK have benefited from the scheme already. In Bournemouth for example, city officials have urged small and medium sized business to take advantage of the offer, according to one of the city’s economic development managers. 

The scheme allows for internet service providers (ISPs), both big and small, to offer high speed broadband services in their localities. One Dorset-based ISP says it is prepared to deploy new superfast broadband infrastructure for businesses. “Too many businesses are running on domestic grade services,” they said.

Dorset County Council, which is just one of many county and city councils involved, says it wants to have at least 500 local businesses signing up and using the vouchers.

Successful applicants can receive vouchers to the value of £3,000, which will cover the installation costs (including appropriate routers) of high speed broadband from your internet service provider. Any additional costs of installation and the subsequent monthly subscription fees will be the responsibility of the business owner from that point forward.

More cities are itching to get involved too. John Stevenson MP in Carlisle is pushing hard for his city to be accepted into the program. “Carlisle is home to many SMEs and I do not want them to be disadvantaged,” Stevenson said.

He added: “We have a good case to make and the outcomes could be quite significant.”

All broadband vouchers are available on a first come, first served basis and the program urges interested businesses to apply as soon as possible to ensure a place on the scheme.

A Review Site that Gives you all of the Battlefield News

I had been searching for a long time for a site that would give me all of the up to date battlefield news. I had about given up on ever finding a decent site to get reviews of all of the latest game play. Then a friend of mine suggested the site that I’m using now and I have to admit that he was right. The news is up to date, fresh, and actually very helpful, which is something I can’t say for some of the competition out there today. If you are looking for the best site around for reviews then you might want to check this one now soon.

Isn’t Medicare (Medigap) Good enough to cover your Insurance Charge?

medigap form medigapinsuranceplan.netWhenever you become entitled to Medicare, you quickly realize that it’ll cover considerably less than half  some say just one third, and also the percentage is dropping every year of the actual healthcare costs what is medigap. This gap in coverage can amount to a staggering amount of money in a very small amount of time. In 2004 it had been possible, with complete Medicare coverage, to operate up out of pocket hospital expenses of about fifteen thousand dollars in the first five months that you simply became entitled to Medicare. Whenever you understand that that does not take into account additional charges from physicians, consultants, tests, and therapy (especially from providers who don’t accept a job), it is not confusing why it is a wise decision to take out a policy that picks up some of these uncovered costs. Low medicare rates at http://www.medigapinsuranceplan.net/.

No matter how high a premium you really can afford, however, you can’t buy a policy that will purchase all the expenses you will have in connection with your health care. The very best you can aspire to do is get the most complete coverage available and be clear about its limitations. The kind of policy to look for is called Medicare supplement. The us government is really aware of the inadequacy of Medicare coverage as well as the necessity of supplementing it that even though it has sharply reduced the number of publications offered to consumers, it provides a slim brochure on Medicare supplement policies. In addition, both state and federal governments have passed laws protecting consumers against a few of the more blatant questionable practices by some insurers in this region.

Medicare supplemental insurance polices are sometimes known as Medigap policies, however this can be a misnomer; it might be better to call these policies Medicare gap helpers. The government calls them Medicare supplemental insurance policies, but even this name does not place the prospective purchaser on notice that many gaps will still not be plugged. In thinking of safety nets, it is important to remember that nets have holes and they’re often big enough to fall through.

It is an unpleasant fact that all Medigap coverage is expensive. Before the runaway inflation that prevails in the health provider market is brought under control and health care costs be rational, insurance that commits itself to covering a few of these costs will be equally overpriced. Many seniors who actually have Medigap policies are being forced to cancel them simply because they can’t afford them. Let’s hope that Medicare is less presently appears possible also priced out of their reach.

Using the cards so obviously stacked against them, what are Medicare beneficiaries to do? At least be sure you are getting the best value for your premium dollar. Just like many other purchases, price is only a rough help guide to quality; merely a detailed comparison of the benefits offered and also the gaps to become filled by two or more policies will show whether an insurance policy is fair or a scam more her www.cms.gov.
