There may be a bit of a delay whenever you create an account or sign in or use any other page that has a Google Captcha field in it.
The delay is caused by our workaround for the issue, and we should be able to remove that delay soon.
For some reason our server is trying to access the Google Captcha authenticator via its ipv6 address, which times out and then drops back to Google's ipv4 address. But this address lookup timeout of maybe 30 seconds was happening too slowly for the default 10 second timeout on the captcha check script.
So we still have a mystery to solve! But at least those essential services are now working again.
