If WhatsApp is down for you, you're not alone.
The messaging app appears to be experiencing its second major outage since being acquired by Facebook in February for $16 billion (£9.6 billion). Users have been reporting on Twitter that the service is either simply not working, or is super slow.
The problem began around 14:34 BST on Wednesday, according to DownDetector.com, a site that monitors Web outages. WhatsApp has yet to confirm the outage on its WhatsApp Status Twitter account, and did not immediately respond to a request for comment.

The latest service disruption comes after WhatsApp was hit with an outage back on 22 February, just days after the Facebook acquisition. That outage lasted around 3.5 hours.

WhatsApp did not say exactly when it set the new record, but tweeted that it processed more than 20 billion inbound (sent) messages and 44 billion outbound (received) messages by its users on that day:
