No, I've altered DNS and seen many thousands of connections continuing from these providers even after low value (300) TTL records have been changed several hours previously. I've observed this on a number of occasions.
In the case of Virgin Media, they have transparent proxy caching on some parts of the network I believe, so it's possible this caching was happening there rather than on the DNS servers themselves.
- tricknik 16y agoWell, not much that can be done about caching proxies. Regarding DNS, have you been able to look at whether the IP's from failed requests show up on the new IP shortly after? I.E perhaps browser-pinning from open sessions?
