Re: [GTALUG] Cache DNS issues.

| From: James Knott <james.knott@rogers.com> | What's your cache time? A cache will typically hold the data for a | short time, to keep stale data from propogating. It might be as short | as a few minutes. A cache certainly won't survive a reboot. I don't know about local policy, but each DNS record has a TTL which is supposed to limit the time it is cached. I imagine that these are generally honoured by a caching server to avoid overloading the other servers.
