This is out of scope for the WG list. However there may well be ops people from ISC who are here. You should probably send questions about DNS operational issues (for instance routing problems or service outages) to dns-operations@oarc.net and/or the appropriate fora at the relevant IX. Contact data for ISC's NOC is also on-line. I've chosen not to provide that so you can find it for yourself. That way, you'll hopefully remember how to contact them the next time. If there is one.

You mean dns-operations@dns-oarc.net :-) Regards Denesh (wearing my DNS-OARC hat)
