Users around the world reported that they were unable to send messages, and WhatsApp confirmed these problems at 12:16pm PST with a tweet stating “sorry we currently experiencing server issues. we hope to be back up and recovered shortly.”
WhatsApp started to work again for some users at 2:30pm PST after around 150 to 210 minutes of downtime. Some users reported that “last seen” stamps vanished from their conversations when WhatsApp first came back online, but now some say they’re appearing again.
