Google is moving quickly to adjust its Gmail systems after a disruption left some of its users unable to access the service for nearly an hour.
The company reported that between 17:42 and 18:46 UK time on Tuesday it had been working on a partial disruption to the mail service. The issue is now believed to have been fully resolved.
"The problem with Google Mail should be resolved," the company said in a status update.
"We apologise for the inconvenience and thank you for your patience and continued support."
According to Google, the disruption had left some users unable to access the service. The outage is thought to be limited in scope, impacting roughly two per cent of all Gmail users.
V3 offices in San Francisco did not note any significant slowdown or disruption to the service.
Within 45 minutes of the first alert from Google the company said that it had begun restore service and work of a full fix was posted by the company some 64 minutes after the investigation of the issue began.
Major outages have plagued other service providers as well. Last year Virgin Media drew the ire of customers over an extended outage for its mail services. In March a mishandling of Leap Day in Microsoft's Azure platform lead to an outage of the G-Cloud service.
