Diablo III in Europe Down Since Sunday
Error 3006 with login servers on Blizzard games in the EU region (Update)

For Diablo III, trying to log in on the main EU servers can give results such as Error 33, Error 3006, and Error 3003. The main European Technical Support thread about the issue has many posts by the Blizzard Customer Service support staff. At this time, there is still no resolution:

When I go to a restaurant and they make me wait over one hour for my food they usually give out some drinks on the house. Im not the kind of person that will ask for something as a compensation but telling me you are sorry doesnt cut it ether.
As you already have our money you could care less if a game we payed for isnt available to play. However, YOUR PR IS GOING DOWN THE TOILET! Keep up this good work of yours and people will stop buying your products.
Honestly AlphaLucifer we do care, whilst we work for Blizzard the vast majority are gamers too and we're just as unable to play right now as everyone else (for those that have the luxury of being at home and not here working on the issues right now).
We spend a great deal of time and resources on all our games and one of our core values is to commit to quality, the issue ongoing at the moment though is a unique one and not something that can be resolved by reboot a single piece of hardware or swapping something out with a spare.
How is it possible that all the other EU login servers are up for WoW etc .. But not for Diablo ?
Is it because there is more priority on the 'payed' games ?
Our game services are built up across across multiple systems and in difference places, it just so happens that in this case, the issues are those that are impacting the login related to Diablo III and the Hearthstone Beta, as WoW and Starcraft II work differently, they are luckily not impacted right now.
Besides that support thread, the main place for updates is the Blizzard CS EU Twitter account. Some of the recent updates there involve instructions on how to log in to the EU World of Warcraft and Starcraft II, as well as promises about future updates for the Diablo III and Hearthstone downtime.
REMINDER: #SC2 and #WoW are operational. To login, use the 'Go Offline' option in the #Bnet Desktop App or run the .exe directly.

The #Bnet connection issues are obviously our top priority right now and we will communicate further on this later tonight.

We are sorry for the frustration caused by the #Bnet connection issues and assure you we're doing all we can to get you back in the game.

Ironically, the PTR for patch 2.0.1 is fully functional, and accessible by players around the world. The PTR servers are located in the US, so they are not affected by this battle.net login issue in Europe. For European Diablo III players who want to play in the live servers, keep an eye on the thread and Twitter account listed above, for updates about when the main game is once again accessible to play.
Update: The Europe Diablo III servers are back, and players should no longer be seeing errors when trying to log in. The official announcement:

UPDATE: This issue has now been resolved and you can now access the game once again. Please restart the Battle.net Desktop App if you are unable to login correctly. We sincerely apologise for the inconvenience and frustration caused by the downtime.
Update #2: A final Blizzard Customer Service post explained what caused the issue, that is now fully fixed.

We experienced a hardware issue which affected some of our login severs, which in turn affected access to EU Hearthstone, Diablo III and the Battle.net desktop app.
It took us longer than we expected to resolve this, for which we apologise. However this is now resolved.
This issue is now resolved, and login to EU Diablo III should be able to happen normally.
