Social media sites Facebook and Instagram are down as Meta experiences a global outage.

Facebook users worldwide have had been logged out of their profiles, while Instagram has been unable to refresh recent posts.

The outage began at around 4pm Irish time, systemic internet issue is likely to be the root cause.

Google’s ads status page reports a disruption to the company’s Ad Manager beginning at about 3.30pm GMT. The company said it was investigating reports of other issues.

According to the Irish Times, the company’s hiccups are more contained than those of Meta, with most consumer-facing services, including Search and YouTube, still up without issue.

The outages are unlikely to be as severe as Facebook’s 2021 outage, when a configuration error in a little-known protocol called BGP led to the company accidentally deleting its own address from the systems that allow servers to talk to each other on the internet.
