JavaScript errors on recently posted Questions -- cache server?

Three Questions posted this morning all come up with "the same" ERROR 500 from JavaScript, included at the end of this topic:

Other Questions, posted both before and since those three, appear to be just fine. Was there a server glitch? Caught in the filters? Deleted by the authors?

UPDATE:  More than just these three questions are affected, but there is no clear pattern.  Some Questions seem to be fine, others generate the error.  Perhaps one of the cache servers is hosed?

Looks like a problem with the category. Should have it fixed shortly, thanks for the report!

BUMP! More than just these three questions are affected, but there's no clear pattern.
