I, for my sins, am required to install AOL on some of my customer's PCs on an almost daily basis (not my ISP of choice, but anyway).
I have noticed that it is giving more grief than it used to in the last few weeks. I would guess that something is up (or down really) at AOL since these events occur around SW London without a definitive pattern.
On the other hand I have never been able to get Tiscali to work anywhere, so I guess AOL's not that bad, usually...
