I discussed with Ernest on #python-infra. It was an issue with the DNS 
"resolving the host back to 127.0.1.1 (...) so vsftpd is telling users to 
connect back to themselves".

Just curious if it was some regression or infrastructure related issue in 
pythontest.net ?

Related issue in the past due to disk space issue35386 . When I first created 
the issue opening the FTP URL on Firefox used to give me result or raise 425 
Bad IP error but now it's now consistently returning "500 OOPS: 
vsf_sysutil_bind" consistently.

[issue36131] test.test_urllib2net.TimeoutTest ftp related tests fail due to ftp://www.pythontest.net/ being unavailable

[Karthikeyan Singaravelan]

New submission from Karthikeyan Singaravelan :

I am seeing this error on Windows and Mac CI builds where FTP related tests in 
test.test_urllib2net.TimeoutTest are failing. It's reproducible locally too 
where the tests are skipped on Mac and Ubuntu. Not sure if it's random since 
several PRs in the last few hours fail with this.
