For the record, the stats on this site are collated from testing

servers which some ISPs host for Zeus.


The top three in the UK (testing from the UK) are always Demon, GX

Networks and Easynet. Guess which three UK ISPs host the test

servers...


The tests done from the US (testing the UK-based web sites) are done

from a machine on UUNet's network. UUNet-based UK websites fill 9 of

the top ten machines in this category.[1]


The Zeus figures for "availability" are flawed because availability

of a server may have nothing to do with the ISP hosting it. For

instance, they (Zeus) test my employer's server for availability and

they never get 100% despite the server(s) concerned having had no

downtime whatsoever.


Bottom line, people - measuring ISPs performance is not an exact

science.
