Websites on the Internet are mostly constantly up and running. However, there might be times when some websites may go offline without any notice of downtime. Users of that website would then not be able to access it or use its services which could cause problems for them (for example lost business opportunities). To overcome this issue of missing out on any downtime for your website, it is advisable to subscribe for a service like Robotalp that automatically notifies you as soon as there is a change in the status of your website.
Many of us spend a lot of time working on the computer. It is easy to get lost in your own world while surfing the net, writing reports or even checking your e-mail. When you are hard at work it can be very frustrating when things like slow sites, bad connections and website downtime interrupt you. There is no need to keep checking the website every five minutes and then be disappointed and annoyed when it's still down when you get back.
Why do websites go down?
The website down and the "Server not found" error messages indicate that, you can't access a web page. Therefore, when a domain is not accessible by any means (including ping, HTTP request or DNS server), it is considered as "downtime". You will need to check out what exactly causes this issue - Sometimes it might be only your computer that has the problem, or it might be an ISP (Internet Service Provider) network problem. If you are attempting to access a website over the internet, and getting "Server not found" as a result of this - then your first step should be to check whether the domain is accessible from another computer. If you cannot access a web page from another computer or local network - Then this problem should be fixed by your ISP (Internet Service Provider). If the site is down on a worldwide level - Then it should be related to the server.
If you can access a website by directly typing in its address into the browser - Then the problem might be on your computer itself. Sometimes malware or adware can cause this issue, so beware! Also some programs that you might have downloaded and installed on your computer can be the reason why you cannot access a specific domain name.
If none of the above methods help in finding out if a website is down or not - Then it must be related to the server where that domain is hosted. Server downtime happens for various reasons, including hardware issues (i.e. if the hard drive is not working correctly, or there are some issues with memory) - This type of downtime happens very rarely. However, most common causes for website downtime would be software - including the web server itself (e.g. due to a system update or new installation), or some plugins/addons that you might have installed on your website.
What should i do?
There are a lot of different website monitoring services available on the market today. You can choose to use different ones. This should help you understand which option suits your needs best. Notifications differ from person to person - some people might want SMS notifications while others might only want email ones - I recommend trying out one of the options and seeing if it works for you.
It is important to state that there are many different ways in which you can monitor a website's status and these methods include:
1. Website monitoring service
Most of the websites on the Internet are hosted on a server. If one of those servers go down, it affects all users that try to use that website. Notifications can be received about this through many channels. One way is by email. For this you need a website monitoring service that monitors your website and sends emails when there is something wrong with it.
One of the easiest ways to monitor a website is to use a website monitoring service. You can sign up for one of these services, after which you will be notified when your desired website goes down through an automated notification sent directly to you.
2. SNMP Monitoring Tools
SNMP stands for Simple Network Management Protocol and it is used to manage all devices on an IP network (whether these be switches, routers or servers). An example include the Cacti MIB Browser which can be used to monitor your website's usage stats.
3. Command Line Tools
Finally, there are some command line tools that can either monitor HTTP responses or even ping your website manually on a regular basis to determine whether it is up or down.
there are many different ways in which you can monitor the status of your desired web page. Some methods involve setting up automatic email alerts whilst others enable you to set up various web-based services which can monitor your websites status for either a free or fee based service.
