I'm wondering the same. Can't collect the skyshards, can't even finish two WBs because there is absolutely nobody around to do them because they lined up another event after the zone went live. I'd normally have them done day one. But since last Saturday, I have been signing on at random times, even during "prime times", and waiting by one WB for up to 10 minutes, not a single player comes by, not a single zone chat message pops up. I guess we're waiting another week to finish the zone...
My guess would be that ZOS doesn't want to release a patch on a US holiday (Thanksgiving) when a lot of staff who would normally be handling that and monitoring for issues are going to be off until next week.
We are getting Vengeance 4 next week starting on Dec 3, and all Campaigns need a maintenance beforehand to spin them up and down correctly, so they may just be putting the incremental together with that maintenance we'd expect between the 1st and 3rd.
