For World of Warcraft: Forever players, the “Beta Going Down for a Couple Hours” notice described a planned interruption rather than a confirmed completed outage. Wowhead reported that Blizzard intended to take the beta offline for maintenance and internal tests, with the downtime expected to last no more than a couple of hours.
A Blizzard forum statement reproduced in Wowhead’s report said the beta realms should go offline at 8:00 a.m. PDT. The available notice does not provide a calendar date for that time.
For players, the practical interpretation is that beta access was expected to be temporarily unavailable during the maintenance window. The evidence does not establish that the shutdown or tests occurred, how long any outage actually lasted, when the realms returned, or whether the work involved a new build, patch, character wipe, content change, or change to beta access.
