From EverQuest2.com:

Beginning at 7 AM PDT (15:00 BST, 16:00 CET) on Thursday May 19, 2011, the Login Server, SOE Account and Commerce flow and the Station Store will be unavailable due to maintenance. We expect this maintenance to take approximately 2 hours. This may also cause some forum accounts to temporarily lose permissions, due to the inability to verify account status while the maintenance is taking place. This is only temporary and normal permissions will return automatically once the maintenance is complete.

We apologize for this interruption and will resume all affected services as soon as the maintenance is completed.

From the EQ2 Forums:

All SOE forums will be undergoing maintenance on Wednesday, February 2, 2011, from 10:00am PST until around 11:00am PST [18:00~19:00 GMT].

During this time the forums will not be accessible. We will return to regular functionality as quickly as possible.

We apologize for any inconvenience!

Ashlanne has posted this over on Station.com:

Beginning at 12am PST on Tuesday, January 11th, ALL SOE games, subscription and commerce services will be unavailable for maintenance. We expect this maintenance to take approximately ten hours.

This might cause some forum accounts to temporarily lose permissions, due to the inability to verify account status while the maintenance is taking place. This is only temporary and normal permissions will return automatically once the maintenance is complete.

We apologize for this interruption and will resume the affected services as soon as the maintenance is completed.

I suspect this has something to do with DC Universe Online which launches worldwide on 1-11-11 but that’s just a guess on my part.

Update:  News of this downtime has now been posted on Everquest2.com with conflicting estimates of how long things will be down:

An unexpected server downtime has been reported with login and authentication servers offline. More as we have it.

A tongue-in-cheek Update from Brasse:

Tha Internetz are down at SOE-SD. My team would be happier about it if it did not impact their ongoing “testing” of Dungeon Overlord.!

Update 1:22pm PST: Login & Authentication Servers are back online.

Players on Butcherblock, Crushbone, Everfrost, Unrest, and Guk just received the following message:

Greetings Norrath! The server will be coming down for a brief update at 02:30 PM PST [22:30 GMT] Wednesday December 22, 2010. Please find a safe place to log out before the server comes down.

We’ll let you know when we find out the cause of this unexpected downtime.

UPDATE: This update is apparently to address an issue with illusion forms and will require the servers to be offline for approximately 1 hour. Amnerys has posted an announcement.

Rothgar checked in with this announcement on the EQ2 Forums:

Monday morning will be a short maintenance in order to prepare for more upcoming mergers. The offical announcement should follow soon, but this should be a typical 7am downtime with 30-60 minute ETA.

Monday night at midnight we will begin our next merger with Unrest and Najena. Estimated downtime as with the last merger will be 24 hours but we hope to have servers up earlier. Several minor issues with the last merger have been fixed so we expect this one to go smoothly. We will do our best to keep you updated with the merger progress as it is happening.

From the EQ2 Forums:

Beginning on Thursday, December 9th, at 1:00 am PST (9:00 GMT), the following SOE Services will be unavailable or interrupted while we undergo data center maintenance.

• Chat Services
• All Star Wars Galaxies Servers
• All EQOA Servers
• All PlanetSide Servers
• All EQ servers
• All Vanguard Servers
• Session (Game Log-In)

We expect this maintenance to take approximately 11 hours, with a return to normal functionality around 12:00 pm PST. During this maintenance period, some game servers will not be accessible. During Session maintenance, some servers may remain online, but players who log out may not be able to log back in. This maintenance may also affect the ability to log into our forums.

We apologize for this interruption and will resume the affected services as soon as the maintenance is completed.

Players are reporting in the chatroom that Splitpaw has been down for approximately 30 minutes.

From the EQ2 Forums:

From 1:00 am PST (09:00 GMT) until 1:00 pm PST (21:00GMT) on Tuesday, December 7, SOE account services, commerce flow, and the Station Store may be unavailable during maintenance. Session servers (the ability to log into games) may also have interrupted service during this time.

All Battlegrounds servers will be locked during this maintenance.

We apologize for this interruption and will resume the affected services as soon as the maintenance is completed.

then…

Runnyeye and Splitpaw are being kept offline a little longer while the team inspects an issue that has, well…several NPC’s seem to have forgotten to get dressed when they woke up from the downtime! /blush

We apologize for their indecency and the fact that the servers will take a little longer to be brought back online.

and then:

I don’t have an official up time for the server, but based on the emails I’ve seen, it seems like it might come up around 2:00 am PDT, which would be around 10am London time, if I’m calculating correctly. Around three hours after the original planned up time.

I’m very sorry about the delay, everyone. Fingers crossed that the NPCs decided to finally get dressed and everything else is right as well.
