Why Do My Domain Requests Still Go to CDN PoPs After My Domain Name Has Been Disabled and Domain Resolution Has Been Changed?

Possible causes:

• The carrier and users have cached the DNS resolution result locally. Before the cache expires, domain requests are still sent to CDN points of presence (PoPs). They will be sent to the new DNS record only after the cache expires.
• Before the domain name is disabled, a user pings the domain name to obtain the IP addresses of CDN PoPs, and then binds the domain name with the PoP IP addresses in the local hosts file. It means that the user specifies a resolution to bypass normal DNS resolution. As a result, requests from the user are sent to CDN PoPs.

Solutions:

• If the problem is caused by local cache, wait until the cache expires.
• If a user binds the domain name with CDN PoPs in the local hosts file, the user needs to unbind them.
