hi
yesterday eve about the same time (but i am in bulgaria) i to had problems with the internet.
for some reason i could not use the internet due to the DNS server not responding, this went on for hours then all went ok.
BUT what i am trying to say is that each computer/internet connection use's a certain DNS server, this then sends and receives your information, there are many servers so not every user would have been affected.
it seems that you been in uk and i been in bulgaria use the same server.
some time ago i could only get a few uk websites and others were just not available and the bot logins failed but not all my bot applications, some could login.
again this was due to the dns server been different for each website.
hope this helps you to understand
