Reports across the world indicate that Gmail is down or impaired in multiple countries though some areas are working normally.
Some people report being able to use html to post an email. Others report a complete inability to work at all.
Outage.Report indicates there have been 1267 reports in the last 20 minutes. (To put that into perspective, there were only 36 reports per 20 minutes on February 12 the last time outages were reported.)
Gmail has been having issues since a little after 7 p.m. Pacific Standard Time but as of 8:17 p.m. pst hasn’t issued an official statement.
UPDATE 9:46 p.m.: Although Gmail is still experiencing some problems, the numbers of reports have dropped drastically. Most local users (including us) no longer appear to have an issue.
