I was having problems connecting to some UK and US sites last night. .CH and .DE seemed fine.
For a period I could not open any connections at all.
traceroute was giving dodgy results. I had to resort to leeching from one of the open Wi-Fi routers within range of my PC.
Seems better now, though not 100%.
These appear to be involved (I've obscured my IP address):
But this one works better
