Same thing has happened to me, only it happened while I was still using version 7. So I upgraded to 8 in case that was the problem, but it wasn’t. I have not been able to sign-in for a week now, and nothing in IM is accessible. Email to Yahoo Tech Support gets the standard “We’re aware of this” but that’s all.

I doubt that a company the size of Yahoo can be technically so incompetent. There has to be a commercial reason for this: probably just bandwidth costs.

But whatever it is, Yahoo have forfeited all credibility here now, and I have not been slow to tell my contacts why. We have switched to Skype, which gives us full screen video and a much more reliable connection, and if that goes belly-up too I’ll damn well write my own p2p program.

If and when Yahoo ever comes back, I shall copy my encrypted legacy data to ascii files and then dump it for good.
