Blizzard's Website Under Maintenance
Maybe a bit late :-)
I was wondering all day today if I was having internet issues yet again, since I could not get to Blizzard's site. Alas, it was just their site undergoing maintenance. Looks like its working now, though if you experience issues this weekend it may be a due to this.
We're currently undergoing an extensive maintenance on our web infrastructure in order to provide new features along with increased performance and security to our customers. As the maintenance continues, some website features will be intermittently unavailable such as account creation, password recovery, Paid Character Transfer, and/or adding payment. We will provide an update when everything is complete, thank you for your patience.
