Hi, Does anyone have a contact for Netvision's NOC? Can't get any response from noc(a)netvision.co.il, and they're causing me some operational issues. Thanks Tony

Hello and Good Morning, Are there reports of L3 having issues this morning ? Starting at about 10:10 A Pacific, I started seeing huge drops in traffic at various sites, including San Diego, Houston, San Antonio, Charlotte, NC, Philadelphia, etc. Anyone seeing a similar behavior ?

Seeing a big drop in outbound traffic on our L3 link starting about that time (we're a web host). Getting calls about sites down too; all the traces I've walked customers through so far have died on L3 networks.

DNS DoS ???
by Elliot Finley 01 Aug '11

01 Aug '11

my DNS servers were getting slow so I blocked recursive queries for all but my own network. Then I was getting so many of these: ns2 named[5056]: client 78.159.111.190#25345: query (cache) 'isc.org/ANY/IN' denied that is was still slowing things down. I've since written a script to watch the log and throw these into the box local firewall. If I expire the entries after 24 hours then I accumulate about 10200 unique IPs. If I expire after 48 hours, then it's just over 20000 unique IPs. Is anyone else seeing this? Elliot
