Update 3: Google claims the issue with Gmail is resolved.

(2:31PM PST 11/25) "The problem with Gmail should be resolved. We apologize for the inconvenience and thank you for your patience and continued support. Please rest assured that system reliability is a top priority at Google, and we are making continuous improvements to make our systems better."

Update 2: The issues appear to be resolving.

Update: Google has marked Gmail as experiencing a service disruption currently:

(1:11PM PST 11/25) "We're investigating reports of an issue with Gmail. We will provide more information shortly."

If you're experiencing slowdowns or failures to load in Gmail, Search, Drive, Maps, YouTube, or other Google services right now, you're not alone - there appears to be a relatively (geographically) widespread issue causing problems.

Google's own apps status site is still showing all green, though even that is loading incredibly slowly for me at the moment. The outage does appear to be regional in nature, but we haven't seen any areas seemingly more affected than others. Out here in Los Angeles, I'm getting problems with pretty much any Google site at the moment. We'll update this story if Google does acknowledge the outage, though they tend to take a while before that happens.
