Re: Unlucky if you live in one of these areas
I'm also in Essex, slightly further from the M25, just after midnight yesterday night my connection dropped for about 30 minutes (which was unusual)... And all of yesterday night it had been sluggish (I've long since dumped the HH3 and BT's dismal DNS servers, so they're not the problem). Speedtest looked like everything was okay, but other sites were suffering.
Same timeouts of traceroute that others describe. Basically looked like routing was fubared.
I tried turning everything off and on again (I'm an IT professional after all), no change, so I gave up and went to bed.
Haven't checked it today.
