Sun Aug 5 18:09:00 PDT 2001 — Dial-group issues. From about 17:30 -> 18:00 some customers were receiving an ‘all circuits busy’ message when calling 522-1002 or 522-1003. I rebooted the last HiperArc card in Nas22, and all is well. — Eli

Wed Aug 1 11:22:48 PDT 2001 — Our own web servers, which are not vulnerable to Code Red, are currently logging around 40 attempted Code Red attacks per minute. Our servers host about 2500 unique IP addresses, so we could guess that each IP address is being attacked about once per hour currently. The ramp-up has been slow, but it’s getting faster and faster.

We’ve searched for vulnerable systems connected to our networks, and have informed customers when we’ve found problems. We also currently have inbound port 80 blocking (web) in place for dynamic dialup pools. This will not affect normal use of your dialup connection, but protects you from inbound worm attacks in case you’ve got a vulnerable Windows NT or 2000 system. -Dane, Eli, Steve, Russ, Scott and Kelsey

Wed Aug 1 10:05:03 PDT 2001 — A Code Red firewall filter installed on pm3 caused some people who dialed into 707-522-1001 to lose connectivity this morning. We removed the filter and the connectivity came back. Sonic.net has invested in multiple dialup numbers in each area we cover, so that there is always a number that will work for you. It is always a good idea to keep a current print out of backup numbers for your area when problems may arise. You can get a current list of dialup numbers for your area by using our pop finder tool which is located at www.sonic.net/cgi-bin/pops.pl -Steve
