Some of you will be experiencing some connectivity issues trying to connect to Battle.net (including Blizzard’s website) this evening. Blizzard are aware, it appears it may be a repeat of the problem they had at the weekend. Here are a couple of tweets about it.

It’s even a little difficult getting to that link in the tweet above. If you can reach it, it says
We are currently investigating today’s reports and will be sure to update this thread as soon as more information becomes available. We sincerely apologize for any inconvenience this service interruption has caused and thank you so much for your patience. We hope to have our Battle.net service restored and running smoothly just as quickly as possible.
In the meantime, until these issues can be resolved—or, in the case of a distributed denial of service (DDoS) attack, they subside—we recommend that you exercise caution if playing on a Hardcore hero.
Hi all, we're investigating the current log-in/connection issues that are not unlike what we experienced over the weekend. Updates to follow

On investigations it does appear to be the same group who were doing the rounds with DDoS attacks at the weekend.
