According to the German Wikipedia, some software vendors use 9xx for proprietary error codes, which have never been mentioned in the RFC. They are probably save for non-standard use. https://de.wikipedia.org/wiki/HTTP-Statuscode#9xx_%E2%80%93_Propriet%C3%A4re_Fehler -- https://mail.python.org/mailman/listinfo/python-list
