Many Irish social media users are experiencing problems with Facebook, Instagram and Messenger this morning.
Down Detector is showing that all three have seen a surge in issues since 9am.
While the reason for the issues remains unclear, of those who reported problems, 80% said they weren't receiving messages, while 20% couldn't log-in.
The Mirror has contacted Facebook for comment.
Unsurprisingly, several frustrated users have taken to Twitter to question what's going on.
One user wrote: "Is Facebook Messenger down? I cannot send and receive messages!"
Another said: "Either Facebook messenger is down on my phone or my wifi is extremely poor this morn. Let me text my friends back!"
And one added: "Yeah so Facebook messenger be down or I’m really trippin."
Worryingly, DownDetector has also issues alerts for Facebook and Instagram - two other Facebook-owned apps.
