Choosing a good web hosting to your site might be crucial. An internet site which is down or malfunctioning could mean loss of business and sales. There are many factors to consider when choosing a hosting for your site. One of them is up-time, which is the total time your site has been accessible to internet users.

Netcraft measures the response times of around forty leading hosting providers’ sites. The performance measurements are made at 15 minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.

As of February 2010, the most reliable hosting service, according to Netcraft, is Navisite, which had no down time and no failed requests. The second place goes to Datapipe, and INetU is in the third place.

According to Netcraft:

From a customer’s point of view, the percentage of failed requests is more pertinent than outages on hosting companies’ own sites, as this gives a pointer to reliability of routing, and this is why we choose to rank our table by fewest failed requests, rather than shortest periods of outage.
