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.
To use the CacheCheck go here:
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 can cache a domain for full time-to live (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.
Issues with domain resolution:
If you have flushed our caches but the domain you are trying to reach is still not resolving correctly please open a support ticket through the Support tab in your dashboard or by emailing email@example.com describing the issue. Please also run our diagnostic tool with the domain you are having issues with in the optional domain field and send us the results so that we can further investigate.
