https://api.mqcdn.com server is currently unavailable. As a result trying to download https://api.mqcdn.com/sdk/mapquest-js/v1.3.2/mapquest-maps.js fails.
api.mqcdn.com seems to no longer have a DNS entry.
I confirm that there's a DNS configuration error. How can we ask Mapquest to check and restore ASAP correct DNS entries?
I guess they are US based (Denver?), so we wait for someone in their support to wake up? I've sent a tweet to @MapQuestSupport, but unless they run 24x7 then it'll be US time - around 14:00 GMT before anything happens.
I guess even if someone had downloaded the JS, it wouldn't just work from another location, as it probably makes dynamic calls to the same sub-domain.
Although this does sound like a reason to get it also located, and working, from other CDNs like JQuery and others are. It's not on Cloudflare
