When upgrading a the network, I get a error for one of the subsites (not the others)...
Warning! Problem updating http://a-subsite.mymultisite.com. Your server may not be able to connect to sites running on it. Error message: Coundn't resolve host 'a-subsite.mymultisite.com'.
and...in fact, that one can not be found...
Is it because of the "-" in the subsite name or something else because the other subsites update just fine.
