Update (12:15 pm CST): The app appears to be working again, though a couple of complaints are still trickling in.
The complaints appear to be coming from Europe, Asia, and South America, with scattered complaints from other regions. I know I can’t use it here in Texas, and my colleagues in Amsterdam report it’s down for them as well.
Unlike most other social media sites, you can’t exactly check WhatsApp’s Twitter for updates, considering the last time the profile was updated was in late 2016. But that hasn’t stopped hundreds of people flooding Twitter with complaints under the hashtag “Whatsappdown.”
