Hello! In case you haven't noticed, many servers are currently down and crashing! This is a result of a bug in Spigot (which was adopted by MCPC+) which caused server ticks to go negative and break a lot of stuff a little while ago. This has been fixed by MCPC+ already, so if your server host has not already provided an updated server, please use this one: http://ci.md-5.net/job/MCPC-Plus-164/
Neither we nor Mojang have anything to do with this issue, nor can we help aside from pointing you to the right place, but we hope all your servers find their way back to working condition soon! Best of luck!
