Had problems using Google Talk this morning? You're not alone. Google's instant messaging service has been down for two hours for most users.

The problem is affecting both Google Apps and Gmail users, though Google Apps customers appear to be suffering the most.

Google noted the first disruption of service at 6:40 a.m. on its App Status Dashboard. By 6:50 a.m., the disruption was changed to "service outage."

At 8:50 a.m., the company added this note to its dashboard:

"Our team is continuing to investigate this issue. We will provide an update by 7/26/12 9:50 a.m. with more information about this problem. Thank you for your patience."

In other words, don't expect to get a lot of work done using GTalk for at least the next hour.

Twitter isn't down, though, so users are discussing the GTalk outage on the service.

We'll update this post with more information as it become available.
