Snapchat is reportedly down for thousands of users worldwide.
According to Downdetector, the problems started at around 11:50am and so far more than 13,000 complaints have been logged.
On Twitter, Snapchat Support is responding to users who are reporting problems sending snaps.
Snapchat is yet provide an official statement regarding the outage, though.
It comes after Facebook, Instagram, WhatsApp and Messenger went down last Monday (4 October).
Billions of Facebook users were unable to get online during the five-hour blackout, which the company said was 'an outage caused not by malicious activity, but an error of our own making'.
Santosh Janardhan, Facebook's vice president of infrastructure, said that during what was 'routine maintenance work' on the firm's backbone network 'a command was issued with the intention to assess the availability of global backbone capacity, which unintentionally took down all the connections in our backbone network, effectively disconnecting Facebook data centres globally'.
Sounds like someone is in deep s**t then.
Writing in a blog post he said: "Our systems are designed to audit commands like these to prevent mistakes like this, but a bug in that audit tool prevented it from properly stopping the command.
"This change caused a complete disconnection of our server connections between our data centres and the internet. And that total loss of connection caused a second issue that made things worse."
LADbible has contacted Snapchat for comment about the outage.
