Those users looking to get on Apple's iMessage earlier this afternoon were out of luck.
A quick glance at Twitter, however, shows that some users are claiming to still be affected by the outage -- nearly two hours after Apple posted the service being restored.
According to 9to5Mac, 30 percent of iMessage users weren't able to use the service during today's outage. Apparently, whenever they typed in their message and pressed send, they received a "Not Delivered" message in response.
However, the service has experienced a series of outages since its inception. Last fall, iMessage went dark in September, October, and November. And in April, both iMessage and FaceTime went down for many users. It's unclear what caused these outages.
CNET contacted Apple for comment. We'll update the story when we get more information.
