ultimately resolves to

I think the original problem was caused by an unquoted URL with a querystring (ampersands) in it.

Anyway, myvideos.stanford.edu no longer resolves to an IP address. @seanjensengrey https://mvideos.stanford.edu/graduate#/SeminarDetail/Spring/2015/EE/380/6954 gives an error page (yeah, it's been over 3 years...)

I think we can close this.
