We have not seen reports of customer issues, despite the blocks remaining in place, so are marking this as resolved. We continue to advise using an MFA app (vs SMS based authentication) especially for non-US phone numbers.
Early this morning, our captcha provider experienced an issue which led to a large increase of "Captcha Validation Failed" errors when attempting to sign in. We temporarily disabled the check at 7:35 am eastern, and our captcha provider confirmed the issue and resolved it at 8:10 a.m.
Our host was able to scale our capacity to normal levels and this has been resolved. During this period, things may have been slightly slower, but we did not see meaningful increases in error rates or anything more impactful.
