CacheCheck
OpenDNS has huge caches, which is one reason OpenDNS makes your Internet experience faster. With CacheCheck, you can check what OpenDNS customers see when they request a domain. If there's something amiss, you may refresh OpenDNS's cache for that domain.
For domain owners:
OpenDNS gives you unique insight and control into how OpenDNS resolves your domain with OpenDNS CacheCheck. If you are moving a domain from one DNS host to another, CacheCheck can help you make that transition smoother. In effect, you tell OpenDNS to "refresh now," ahead of Time-To-Live (TTL) expiration. Note: OpenDNS never holds domains longer than TTL.
For website visitors:
If you visit a domain and find that it's not resolving, CacheCheck is a way for you to learn more about why that might be happening. In some cases, you can help fix the problem even though you don't control the domain itself.
