LinkedIn is back up after a worldwide outage affecting users on both mobile and desktop.

The Microsoft-owned social network first started experiencing issues around 2PM ET, and LinkedIn confirmed things were back to normal at 4:21PM ET.

The company didn’t give a specific reason for the outage, though did jokingly suggest the issues may have been due to a WandaVision character.

Pardon the interruption everyone. We're back on track now. Unconfirmed reports indicate it might have been Agatha all along. 🎶

It’s rare for LinkedIn to experience outages. LinkedIn last experienced widespread issues in January last year, when users weren’t able to post to the service or make new connections.

Today’s outage affected the entire website, and it wasn’t loading for most users at all.
