Quite. I did have some issue with my server becoming unreachable every couple of weeks at the start of the year for a couple of times. Not sure if it was a fault that I caused or if there was some kind of a networking issue. I know I tinkered with the server a bit earlier, but it seems to have resolved itself without me really doing anything, so it could really be either way.
One problem is also that apparently some Americans have really bad peering to my server. As an European, I can't really confirm if this is the case, but it's what I've heard.
