I've been using the servers in Ukraine for months now. No server downtime (although I haven't checked during this latest drama) and despite being in Ukraine my connection is always maxed when I'm downloading something.
Same here, I get 1mbps download speed on the UK servers, but I get 5-6mbps download speed on the Ukraine server.
I find steam is down a lot lately im actually getting fed up with steam.
I was having problems with it after 8PM yesterday. I wanted to play Skyrim, but Steam said I couldn't because it was still Syncing to the Cloud. I left it doing that for an hour with no change, so I tried restarting Steam, but that made no difference so I gave up with it.
Haven't been on my PC today, but I'd be surprised if it's any different.
