Latest update: The issue now appears to be resolved.
The Blizzard Agent has went offline following a technical error. As a result of the technical error, users may experience slow log in or may not be able to log in to the Blizzard Agent at all.
This means that if you are using a PC, you will be unable to play any of Blizzard’s games which have to be started through the Blizzard Agent. This includes games like Call of Duty: Modern Warfare, World of Warcraft and Hearthstone.
Blizzard has posted the following tweet on the matter:
No ETA has yet been provided for a fix as of yet. I’ll keep you updated of any developments.
