This is the second month running that INetU's site has had no failed requests at all, and it has now been in the top three for the last four months. As neither INetU or Secure Dog had any failed requests, INetU is ranked above Secure Dog because the average connection time from our performance measurment points to the INetU site was faster.
Third was www.pair.com, a consistently reliable site which was placed fourth for H2 2003. All of the top three sites run on BSD operating systems.
Two European hosting company sites made it in to the top 10. Cable & Wireless and Energis, respectively the second and third largest telcos' in the UK were fifth and tenth. Energis is Netcraft's own connectivity provider, but has no special advantage as none of the measurement points are on the Energis network.
Netcraft measure and makes available the response times of fifty five leading hosting providers' sites The performance measurements are made at fifteen minute intervals from four separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.
