Multiple folks are reporting their Sprint DS3 and T1 circuits are down in the Seattle area. Abovenet, UUNET, Verio, Qwest, and more report no backbone infrastructure problems in the Seattle area. A few individual customer circuits are down, but it is likely a problem at the customer site, not with the network. The Seattle Internet Exchange (SIX) appears operating as normal. Qwest/USWEST reports extremely heavy call volume in the Seattle area, and dial tone may be delayed. But there is minimal infrastructure damage to their network. Data circuits appear functioning as normal. Some long-distance telephone networks have messages that calls can not be completed due to an earthquake in the area.

According to ABC News, there was just a 6.2 magnitude earthquake, with the epicenter about 35 miles away from Seattle. It appears that Sprint is having some connectivity issues in the Seattle area, several Seattle routers in sprint's network are unreachable at the moment. Anyone else experiencing problems? -- Kevin

The US Geological Survey has revised the magnitude to 7.0. Due to structural damage in the air traffic control tower the SeaTac airport has been closed down. All railroad traffic at standstill until tracks have been inspected. Cell phones in the area are very congested, and people report difficulty making phone calls in and out of the area. I have not heard if any phone companies have imposed network management controls on voice traffic. Folks have reported in from the Westin Building, the main Internet hub in the seattle area, that no substantional damage to the building. Approximately 11,000 electrical customers are without power.

Anyone give me an idea of what sort of traffic passes to (and hopefully thru!) their MAE-LA peers? It's hard to tell whether anyone cares about this NAP or not, and there appears to be significantly less potential peering partners connected to it. Makes for a tough ROI argument when compared to the other NAPs. While I realize some of this might be a critical mass issue, MAE-LA seems to have been fairly stagnant for several years now. While we're at it, have any input on PacBell's NAP? :-) BTW: Anyone considering connecting to Telehouse's 6IIX IPv6 exchange points at this point? They are collocated inside with NYIIX and LAIIX.

The idea of 'traceloop' reminds me of what can be done with the Ganymede (now NetIQ) Performance Endpoints as used by Chariot, Pegasus, et al. They have a freebie Qcheck tool (Windows only, for the gui, alas) which can do a traceroute from anything running its agent. http://www.netiq.com/downloads/products/Performance_Endpoints/default.asp http://www.netiq.com/products/Network_Performance/Qcheck.asp Binary distribution only, no docs on the protocol (that I know of) but you can deploy it on your own systems, limit access, and generally control what it is allowed to do ('cept for any bugs that might be therein.) Just thought I'd mention it. (Sadly the Qcheck GUI is Windows only, and NetIQ do ask for 'personal' details when you download it, but you can't have everything - just don't put in anyone's who might be susceptible to a sales pitch!)

Re: Warning: Cisco RW community backdoor.

It appears more than one vendor shared the same SNMP library (or SNMP programmer). Folks have sent me evidence at least two other vendor's equipment has similar responses to the same SNMP community string ILMI. However, there are other non-related SNMP issues. Many SNMP implementations included the default community strings "public" and "private". If the operator doesn't change them, the defaults may still work. The other common SNMP implementation issue is if no community string is specified, the SNMP agent accepts any community string. If you are checking your network, I'd suggest checking for all three possibilities.
