It’s not just you! I came into the office this morning and tried to connect to the Google Talk network and it never connected. I checked out the Google Talk Status Page and they are working on a fix as they discovered a Global outage around 6:40am this morning.
The last update as reported by Google was at 9:50am EST,
We are continuing to investigate this issue. We will provide an update by 7/26/12 10:50 AM detailing when we expect to resolve the problem.
UPDATE:
As of 10:50a Google announced the following:
Google Talk service has already been restored for some users, and we expect a resolution for all users in the near future. Please note this time frame is an estimate and may change.
At my office, everyone’s Google Talk has come back; not too shabby Google, 4 Hours to fix a crashed server is pretty impressive.
