Tonight I'm having trouble loading services from Akamai's CDN servers, SYNs go out to port 80, but no ACKs come back and the connections ultimately timeout. If I manually DNAT things on my firewall to a different set, it works, but it seems that TalkTalk are routing me to broken servers. Servers I can't get a response from include:
62.24.201.65
62.24.201.143
62.24.201.56
62.24.201.40
62.24.201.181
And probably others. ITV Player catchup TV is affected at least, and almost certainly other services that I haven't noticed yet...
