10 Best Free Website Uptime Monitoring Services

It  is very important to monitor the uptime performance of a website or blog. The target of such monitoring is to be notified as soon as the website goes down, and immediately take remedial actions to correct it.

Many people are not aware that there are some really good free website monitoring services. These check your website at pre-defined intervals, and alert you (via email, SMS, or RSS) when your website goes down. You do not need to download or install any software to use these services. Simply create a free account, and specify the URL that you want to be monitored.

Here are 10 Best Free Website Uptime Monitoring Services:

1. Pingdom: This one is the most popular service, and my personal favorite.

All these services are pretty good, and can serve needs of all type of websites ranging from personal blogs to commercial websites. If you do not get lot of visitors, you can choose a service with monitoring frequency of 15 minutes or more. If you get a lot of visitors like this site, you want to choose a monitoring service that provides shorter monitoring intervals. Another factor you need to consider is how do you prefer to get alerts. If you do not have access to email all the time, then you would want to choose a service that sends SMS alerts as well.
