Since, [as I I fail to see the correlation still.. anycasted caches should all be operating independently getting their DNS data from authoritative sources. If at any point one of them uses a TTL that it has not received from the authoritative source it is ignoring the ttl, where does anycast get involved with this particular problem? thanks Steve
