Some Gmail users reported emails bouncing and other error messages.
Google (GOOGL) initially said on its status page that it was aware of the outage around 4:30 p.m. ET. “The affected users can access Gmail, but see errors, high latency and / or other unexpected behavior,” he added.
The issues were eventually resolved shortly before 7 p.m. ET, the company said. At their peak, they hit nearly 18,000 users, according to the monitoring site Downdetector.
“You can be sure that system reliability is a top priority at Google and that we are constantly making improvements to improve our systems,” said Google.
On Monday, several Google services went out for about an hour, including Gmail, YouTube and Google Classroom.
