That's USC's issue, isn't it? The file request against their server is failing?
Yes
You should report the issue to Canonical and see if they know what's going on.
No, because The wiki :
https://wiki.ubuntu.com/Valve
no say to report problem at Canonical.
Launchpad say :
Please do not report bugs about software in PPAs on Launchpad. This is because software in PPAs are not provided by the official Ubuntu repositories. Instead, the PPA homepage would have a contact point and preference of the PPA provider.
The problem is not with the PPA, it's that you can't retrieve the PPA. Valve hasn't removed it as far as I know.
Bugs are post in launchpad :
