he,ca,mk wikipedias already have <mapframe>, and need to be updated to the snapshot service, which is also a good test for the snapshot service stability.
I have reached out to cawiki and hewiki on Village Pumps. Got a thanks from cawiki and a translation (but no comments) on hewiki. mkwiki doesn't seem to be using any maps yet, so I didn't notify them. Everything seems ok so far.
