I purged the cache from the CDN and checking more into the DNS. Thanks for the heads up.sta.caraudio.com is currently resolving to a maxcdn server and maxcdn is giving a 502 error...
Did you happen to change the ip address to maxcdn IP or give a incorrect IP?
Either way its a issue on cloudflare you need to look into.
Unless our DNS are resolving incorrectly still from a DNS change which hasnt passed thru?
