Internet Service Providers Ranking by Uptime and Availability

Our community was frequently called upon to perform a research on uptime and availability of different web hosting providers. We were waiting to collect a sufficient amount of data and gain larger coverage before publishing such a report. Now we are ready to do this and we hope that it will be useful to our users.

Considering the amount of websites we are monitoring, we selected sites that belong to large Internet Service Providers (ISP). It was interesting for us to analyze which ISPs are the most popular providers for our community. The top 20 hosting providers are listed bellow. The Test Count column shows how many tests (typically 1 test = 1 website) were added toMonitis by our users.

We calculated consolidated uptime of all the sites that belong to each of these ISPs. The table bellow shows uptimes measured in May, 2007 per 20 top web hosting providers sorted from best to worst:

We are going to publish similar reports periodically. The more our users add sites for monitoring, the better coverage we will provide in our research. I hope our community will find them useful.
