Gmail, YouTube and other services that rely on Google’s technology were disrupted for several hours on Sunday by what the company said were “high levels of network congestion.”

The company first identified the issue on its Google Cloud status dashboard at 3:25 p.m. Eastern time. Google did not say how it believes the problems originated.

Google said the problems were not caused by a cyberattack, as hypothesized by some on social media. As of 7 p.m., Google said the issue was “resolved for all users.”

The company said in a statement that it would “conduct an internal investigation of this issue and make appropriate improvements to our systems to help prevent or minimize future recurrence.”

The sound of millions of cat videos being suddenly silenced reverberated across the internet, and #YouTubeDOWN was a trending topic on Twitter.
