Ah, sorry for the breakage! For the record, there's now an API endpoint for this you might find useful: https://www.worldcubeassociation.org/api/v0/export/public. This should be lighter weight than downloading the whole export just to check its timestamp.
IIRC, Lucas told me about this change in advance, and then I didn't fix it for a month after it broke. So this is entirely our fault, not yours :)
This job runs infrequently enough that this wouldn't save a significant amount of time or bandwidth. That said, I assume this is more stable long-term, so I filed #192 (though I'm not in a rush to address it).
