Review comment:
Just perusing here, but we generally shouldn't make DB calls in a loop
like this. It's better to make a _single_ DB query that gets all the stuff we
need to check in memory and check everything in memory at once, as opposed to
making a DB query per CDN or per delivery service. Especially for things as
numerous as delivery services, that can really slow things down and increase
load on the DB.
