Internet Archive: metadata trouble?

Looks like there's some trouble with items uploaded to the Internet Archive between 10 and 30 days ago.

Here's the error:
"The item you have requested has a problem with one or more of the metadata files that describe it, which prevents us from displaying this page."

At least the items still exist; if they didn't the error would be "Exhausted all choices for locator URLs. Item cannot be found."

The Archive, for all their good points, are notoriously silent about these sorts of problems. A quick note that "Nobody's files are lost, and they'll reappear soon" would go a long way to making Archive users less anxious.

As it is, I'm wondering if I should hustle and look for copies of the currently-missing files on my computers, and ask friends if they've downloaded copies.
