gov.za proxy fail

The *.gov.za services that are proxied behind iproxy1.gov.za all seem to have fallen over, while the services that are proxied behind iproxy2.gov.za seem to be fine:

iproxy1
cemis.wcape.gov.za
www.westerncape.gov.za
www.services.gov.za
www.search.gov.za

iproxy2
www.gov.za
www.info.gov.za

Could be a proxy issue, or maybe Telkom playing games again, or even a local failure. Weiiiird.
