It was... hopefully still is a major priority for them. They've taken serious cracks at it. Sounds like they've managed to reduce the amount but still have a bit to go. I don't see them removing all of maintenance to fix the issue. They are too determined to keep that feature. Plus... taking it away now and restoring it later with have an incredibly negative effect on the community.
We didn't take it well from Alpha... as in most people don't play from those days anymore. Can you imagine introducing this game to the new open beta crowd... only to implement maintenance later? If they are going to keep such a system it's better to let people know now than later.
Remember report your bug to their service and they'll typically refund you. The more logs they get the more they can determine what happened to you.
