You've seen 98.9%, 99.9%, and even 100% server uptime labels on hosting sites. The first thought which comes up to people is, "Well, 99.9% sounds pretty well; 0.01% is no big deal," and they are right. Many people are missing because even if the server is reachable, it doesn't necessarily mean it's fully functional. So many other things can go wrong with a server. A 99.9% uptime sticker is no guarantee that your business won't face different problems while the server is up and running. Hosting providers calculate uptime in ways that aren't intuitive from a user's perspective, not considering certain website downtime.

• First of all, not all downtime is counted. Scheduled maintenance is not part of the equation. Several hours of downtime is not what hosting companies would include. When monthly server uptime is calculated, such planned service interruptions are not included (deducted).
• Some, if not most, hosting providers tend to overlook shorter downtime periods. 3-5 minutes of unavailability are not considered significant and don't end up on the 99.9% sticker. You can see how multiple short downtime periods can make a difference at the end of the day.
• 0.01% means twice the trouble. 99.9% uptime means 8 hours and 45 minutes of downtime per year. So when you go down a notch to 98.9%, your calculated downtime goes up twice to 17 hours and 30 minutes.
• Resources are limited. "Unlimited" is just a nice way to sugarcoat "enough for the majority of common users." Your business might not be a common one, and demand might be high. There might be other significant sites sharing the same hosting hardware. At one point, it can all build up to an overload, resulting in poor loading times, broken transactions, and even a website. The server will remain online, but the performance won't meet your needs. Application monitoring is a good way to quickly and easily discover such problems.

100% uptime is not feasible. Eventually, something will go wrong. Network backbones will cause problems; power failures will happen, server software and hardware will fail now and then, and human error will always be important. So, my advice is: Don't try to find the ultimate provider, as it doesn't exist. Instead, find a decent provider with good server uptime and performance, 24-hour technical support, and frequent backups. Oh, why don't you go for a nice remote website monitoring service, just in case? It might be the best money you have ever spent.

It is quite common to see "404 Not Found" page instead of the requested one. This is a standard status code, informing the client that the server has not found anything matching this precise URI (short for Uniform Resource Locator). In other words, that is what you get when the server is not able to find the page you are trying to load, due to one reason or another.

This status code is commonly used. However, it is not the only error code you might get. 404, along with other 4xx status codes, is a client-side error, meaning that the user either misspelled or requested a page that is no longer there. On a different note, status 200 is the most common server reply you get. You don't see it because the request succeeded to display the requested resource.

Ping is one of the most well-known and easy-to-use computer network tools. Its basic application is to test the availability of hosts across an IP network. The ping tool was written by Mike Muuss way back in December 1983. Its practical use and reliability were undeniable until 2003, when a lot of internet service providers began filtering ICMP ping requests due to growing thread from internet worms and basic DDoS attacks. Nearly 3 decades later, ping stands tall, providing common computer users, webmasters, and network administrators with valuable information.

Check your network adapter

Common users can use ping from their local machine to check if their LAN, WLAN card is enabled and working by simply pinging itself. The command will look something very similar to this:

Your online presence can easily depend on you answering the question - where to host my site? You will probably do just fine with most hosting providers, or in other words - average.  Average is OK, but we can go one step further and place a solid bedrock for your online business.

Where are your visitors?

Think about where your audience is? It would be best if you made your website as easy as possible to reach by finding hosting with good access, quick to reach, and able to load website pages fast. It is good to get a local provider if you target a local group of people, and likewise, it's good to have remote hosting should you be targeting a remote location.

The response time of a webpage is the time elapsed from the moment the user requests a URL, until the request page is fully displayed. This process can be separated in to 3 logical units - transmission, processing and rendering.

• Transmission consists of the time to transmit the user's request and receive response from the server.
• Processing is the part of the operation where the server has to process the request and generate the response.
• Rendering is client side operation and consists of the time needed by the client machine to display the response to the user.
