I can second this. With rate limiting and dampening (at my side) I get customer complains, that the Google webmaster tools report an unreachability of the DNS servers (about 5%). OTOH there are customers which use Google public DNS and do have sporadic resolving problems "Internet is not working! We can't even access our own home page!" And this is true: Google IP ranges hit the dampening limits several times the day. _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
