From the announcements thread:

We've scheduled maintenance for the account/sales server on Thursday (5/23) at 11 AM Pacific. We expect up to about 20 minutes of account server downtime. During the maintenance, new logins to Hero Lab Online and Realm Works will be unavailable, but your service will be unaffected if you are already logged in.

UPDATE: We are delaying this account server downtime briefly. We'll post here again when the downtime will be proceeding.

UPDATE: It is 11:50 AM Pacific and we are proceeding with this downtime.

UPDATE: This has been completed.
