Broken things in 3.3.5 on EU realms

With patch deployed on EU servers a week later, you'd think that there won't be broken things. After 18 hours maintenance:
- in Nightfall/Cruelty BG dungeon servers are down;
- heirlooms have their durability set to 0; [Reforged Truesilver Champion], [Bloodied Arcanite Reaper] and [Dignified Headmaster's Charge] are invisible until repaired.
