The Fifth Server Downtime was an event which began on Saturday, November 14, 2015 and ended Wednesday, November 18, 2015.
It was first discovered when QuestionTues_FTW was unable to connect to the server and informed RDPIsOnCrack, the current owner of the server about it. Due to the circumstances surrounding the Fourth Server Downtime, RDP assumed the server fell victim to a DDoS attack again much like the previous incident. Switching the server over to a different host did not solve the problem as the server continued to crash.
It was eventually revealed that the root cause of this downtime was due to Nerdington setting the /gamerule randomTickSpeed to 5000 as a way to clear trees faster. The change in the gamerule overloaded MC, causing it to crash. The issue was later resolved after RDP reset the gamerule to its default setting.
