Feldon From Domino on the EQ2 Forums:
The festival is now active on those servers (Butcherblock and Permafrost) and has been for a while, but did start almost a day late.
We will extend the event on the affected servers. The Gorowyn city festival on Butcherblock and Permafrost this month will end at 11:59pm on the 8th [07:59 on the 9th GMT]. (The festival will still end on all other servers at 11:59 on the 7th). Apologies for any inconvenience!
