Interestingly enough I had a call from one of their phone engineers earlier today (about a line fault that has been outstanding since last October, would you believe), who asked me to unplug everything so that he could perform a test on the line. He then came back and said that the line appeared clear, but eventually agreed to escalate the fault so that I may get a visit from their engineer or maybe one of BT's.
A bit strange, though don't you think ?
I'll try the Dublin server, although the London one is closer to where I live. I tried the Paris server earlier today and that produced something in the region of ~2400 which is what I normally see when synched at 28xxkbps, as I am today.
