In my absence, about 18% of the network was down thanks to a few data centers deciding to arbitrarily migrate server IPs with poor notification. So naturally, the first thing I did when I returned about 2 months ago was fix or replace those dead servers. Now http://ciisqbg45nggykdl6rjdrq3wc64csga4vkphu66qsi65mypeitqedoad.onion/uptime shows the network's back up to 99% or so.
