Web analytics firm Netcraft has announced that Web hosting provider INetU is the most reliable hosting company site for March 2008, followed closely by Express Technologies, now located at Hosting.com.

Rounding off the top five reliable websites for March are Pair Networks, DataPipe and Swishmail, two of which made it to the top five most reliable hosting company sites for February 2008.

Based in Allentown, Pennsylvania, INetU is an enterprise managed hosting company that has been in business since 1996 and serves Fortune 500 clients including big names like Microsoft, Intel, Northrop and Canon.

According to Netcraft, Express Technologies acquired Hosting.com in June 2004 and the Express Technologies website now points to its new home at Hosting.com. The company also partners with DreamHost to provide managed hosting, server colocation and virtual servers running on VMware ESX.

Netcraft says that three of March's top ten hosting companies run Windows Server 2003 on their main site while two use Linux and two use FreeBSD.

Netcraft measures and posts on its site the response times of fifty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the Internet, and averages are calculated over the immediately preceding 24 hour period.

Netcraft also recently shared the results of its March 2008 survey, receiving responses from 162,662,052 websites.
