Blizzard have changed the maintenance timing for today’s pre-patch, as the login screen now says servers are expected to come up at 6 PM PDT, a 3 hour extension from the previous announcement. Hopefully this will be the only delay for today.

#Shadowlands Current maintenance has been extended until 6:00 PM (PDT). We apologize for any disruption and hope to restore service quickly.
