Windows Live / Hotmail problems

Here at ZDNet.co.uk we've been wondering why we've been getting so many hits today on old stories about Hotmail and MSN problems. I had my MSN/Windows Live Messenger on from the start of the day and all seemed fine.

Well, I just got home and yes, it's all gone pear-shaped - guess I'd signed in early enough from work to avoid difficulties. There's a story or two out there already on the issue, but no-one seems to know what's going on, other than the fact that loads of people are having login (and apparently logout) problems. We'll let you know more as soon as we're more clued up ourselves!
