My friend from Slovenia is having trouble with discord. It eats his messages.
I can't load photos from my friend in telegram and the messages take a relatively long time - multiple seconds! - to get received.
TrackMania players have talked about having input lag.
ycombinator is really slow and reports an error after submitting. "We're having some trouble serving your request. Sorry!" (5th try now, got "unexpected link" now)
Some sites I've found via google results seem to report that they are suffering from slow connections.
Do you have anything to add to this?
