The Ultima Online Account Center/server downtime mentioned in the original account migration notion is set to take place tonight and continue through Friday afternoon, according to the UO Herald:
The Account Center will be down starting 11:30pm tonight, Wednesday the 10th of August and remain down until 4:10pm Friday the 12th of August for extended essential maintenance. If you have purchased gametime, expansions or boosters in the last few days please do not make an attempt to apply them until the account center is back up. Game servers will briefly be down on Friday afternoon, other than this you will able play as normal.
Thank you for your patience.
Should be interesting to see what happens. I’m curious to know if MyUO will function properly, with guild listings, skills, etc.
