I had a recent incident when my local exchange had a tech problem. I became suspicious when several of my friends in adjoining houses lost their internet access. I phoned BT and whichever way I tried, I ended up getting put through to people in Mumbai who insisted in going through my modem/router settings and would not acknowledge there could be an exchange problem. Eventually I got someone to admit there was an exchange problem but when challenged as to why this was not posted on the ISPs system status page they said that local problems like this would not show up. Only large scale problems on the main system network would be be posted on system status reports. Really helpful? I think not.
