I was wondering if anyone noticed an odd external DNS problem happening yesterday
Yes we had some issues as well. We kept getting the following messages: named[4498]: client 127.0.0.1#42127: no more recursive clients: quota reached (We have a limit of 1000 and an average of 25) And we could not get to some of the root servers, ie: a.ROOT-SERVERS.NET So I am assuming there was a DOS attack somewhere which affected DNS traffic. Assumption: The name server could not get to some root servers, the queries kept pilling up and we hit the quota. It looks like it was an issue on the - 14th ( 422333 quota reached) - 17th ( 170472 quota reached) - 18th ( 547309 quota reached) To put it into perspective here are the numbers for the previous 5 weeks: 4228 28 16 856 801 -- ------------------------------------------------------------------------ Jean-Francois Pirus <jfp(a)clearfield.com> Senior Software Engineer Phone (+64-9) 358 2081 Clearfield Software Ltd Fax (+64-9) 358 2083 4th Floor 8-10 Whitaker Place Mob (+64-21) 640 779 P O Box 3901 Auckland, New Zealand ------------------------------------------------------------------------
