Service disruption hits Gmail, temporarily knocks out some syncing and other functions

Update: Google says Gmail is back up and running for all users.

Some users (myself included) may have noticed issues syncing mail changes on their Gmail accounts this morning. Google has now acknowledged on its system status page that a “service disruption” is current affecting the email service. The company says the issue currently only affects IMAP connections to the email service, and while most users will see problems, some may not.

While this isn’t a total outage, users can expect to see slow or nonexistent syncing of their mail across devices for the time being, with other features like sending and receiving mail possibly being affected as well. Google has published the following update on the downtime:

We’re aware of a problem with Gmail affecting a significant subset of users. The affected users are able to access Gmail, but are seeing error messages and/or other unexpected behavior. We will provide an update by 3/30/15, 1:15 PM detailing when we expect to resolve the problem. Please note that this resolution time is an estimate and may change.
This is only affecting IMAP connections to Gmail.

No other Google services have been impacted by the problem.
