External WSDL resource down

[eserte]

The test suite started to fail since some days:

#   Failed test at t/01-whitemesa.t line 32.
# died: [WSDL] could not parse http://www.whitemesa.com/r3/InteropTestDocLitParameters.wsdl into WSDL: Service Unavailable at /opt/perl-5.24.1/lib/site_perl/5.24.1/SOAP/WSDL/Expat/Base.pm line 73.

# Looks like you failed 1 test of 1.

Currently the used wsdl resource emits a 500 server error, and this was also the case four days ago, so maybe the error is permanent?
