Gmail service disrupted in new Google mishap
"We apologize for the inconvenience and thank you for your patience and continued support," Google said in the status dashboard notice.
"Please rest assured that system reliability is a top priority at Google, and we are making continuous improvements to make our systems better."
Google did not disclose the number of users affected or the precise cause of the trouble.
The problem with Gmail affected "a significant subset of users," the company said in a post.
A massive blackout on Monday temporarily disrupted popular Google services such as Gmail and video-sharing platform YouTube, derailing the remote learning, work and entertainment that people have come to rely on during the pandemic.
Other Google services such as YouTube, Maps and search appeared to be operating normally.
The broad outage on Monday lasted about 45 minutes.
Google indicated on its dashboard during that outage that it involved services for "the majority of users."
Already ubiquitous, online services have become more critical this year amid the Covid-19 pandemic, as millions work from home and students take their classes online.
Disruptions to online service providers are not unusual. Amazon Web Services (AWS), the Amazon subsidiary specializing in on-demand cloud services for businesses and individuals, experienced a major technical outage in November.
