In business, downtime is unavoidable. Even restaurants have to close occasionally to fumigate or deep clean, so it’s no great shock that websites sometimes suffer from downtime as well. However, it’s important to differentiate between planned downtime and service blackouts.
When you plan downtime for maintenance or upgrades to your website, you have the opportunity to inform users well in advance and even post a redirect page for visitors that explains why your website is temporarily out of service. With service blackouts, there is no warning and no explanation – users are simply unable to access your website.
While there are certainly times when such downtime is faultless, there are also occasions when service outages could have been avoided. By understanding why downtime occurs, you have the opportunity to prevent it.
As a responsible business owner, you should always use a web monitoring service that will notify you when your site goes down so you can respond immediately, as well as provide reports that help you to pinpoint the problems. However, you should also be aware of the most common causes of downtime so that you can try to avoid them. Here are a few you should know about.
1. Unreliable Web Hosting Service
Many web hosts realize the concern their clients have about downtime. When you’re searching for a suitable web host, you’re likely to find all kinds of claims about how little downtime users experience. A common promise is that you’ll have service 99% of the time.
This sounds pretty reliable until you start crunching some numbers. 99% uptime equates to about seven hours of downtime each month, which equals about three and a half days each year that your site won’t have service. If you’re running a business, this number is unacceptable.
It’s like randomly closing the doors to a retail store three days a year without informing customers. Can you imagine how upset you’d be if you went to your grocery store during business hours and the store was closed with no explanation? What if it was a store you were visiting for the first time? You’d probably never go back.
You don’t want this situation with your website, which means you need a reliable web host. In all honesty, a site that actually delivers service 99.9% of the time is about the best you’re going to get. There’s just no getting around the fact that things happen that even a solid web host cannot anticipate or combat.
2. DNS Issues
DNS stands for Domain Name Server and the easiest way to explain it is to equate it to a phone call. When someone dials a phone number, the signal is routed to the appropriate receiver and the person you’re tying to reach hears their phone ring.
DNS is the system that recognizes website names and then identifies corresponding IP addresses and routes to them, ensuring that people typing in your web domain or clicking links to your site are directed to the appropriate landing page. So what can go wrong?
A lot, as it turns out. DNS issues are not at all uncommon. When you register your domain, the vendor you purchase it from should configure your DNS.
However, when you make changes to your website, there’s always the possibility that you could accidentally enter incorrect information or use incorrect settings, potentially messing with the DNS and causing problems for users.
3. Software Compatibility Issues
Building and maintaining a website requires a variety of software solutions. Even if they’re purported to be compatible, there could still be issues with programs fighting for dominance. Or the plug-ins you use could end up being incompatible, just for example.
The result could be pages that don’t load or even complete website failure. Either way, you need to correct the conflict or you could suffer ongoing issues with downtime.
Hackers may attack you in various ways, by insinuating viruses or malware into your system to wreak havoc, by using spyware to steal information, or by outright breaking in. The result could be damage to your website, punctuated by downtime.
Hackers may go after any business, large or small. Luckily, you can protect against hackers with a proper web application firewall and antivirus/anti-spyware/anti-malware programs.
5. Natural Disasters
Okay, this is not as likely as, say, an unreliable web host, but natural disasters definitely occur and they can knock out service to particular regions or even take down the servers that are hosting your website. The best bet to avoid this is to select a web host that has back-up servers in another location just for such occurrences.
