We have a database that we use to log receipts of all received
messages. That database is having some issues, and our when
application sees that, it decides to hand your clients back a 500 even
though we've received the update. We're working to get that database
stable so you once again see the expected behavior (a 200 response if
everything went fine, a 401 response if you're not authorized, etc.).
This is certainly annoying, but at the very least we're not losing
your updates. Thanks for your patience.
