DataPipe and Rackspace were the most reliable hosting company sites for October 2007, followed closely by Seeweb.
Performance figures - including outage rates - from web security and analytics firm Netcraft, said DataPipe was October's top hosting firm, adding to its top place back in March and second place in both June and July.
Rackspace was second, its fourth appearance within the top ten this year. Seeweb offers both shared and dedicated hosting, and also made third place in September.
Four of October's top ten hosters run Linux, while three - including DataPipe - run FreeBSD. Two of the hosters run Windows Server 2003.
