Updated DNS monitoring
by Rob Thomas 28 Aug '02

28 Aug '02

Hi, NANOGers. I've crafted several enhancements to my DNS monitoring suite. I am now monitoring the gTLD name servers, and you can see the data here: http://www.cymru.com/DNS/gtlddns.html (graphs) http://www.cymru.com/DNS/gtlddnstext.html (text) I have enhanced the root and gTLD name server monitoring. Now instead of only graphing hourly query response, I am also graphing hourly ICMP 8 0 ("ping") response. This may provide some additional insight during periods of high latency; it may instead be specious as all get out. ;) You will find it here: http://www.cymru.com/DNS/index.html On a related note... Are you lame? Being lame means I will pick on you during my next presentation. Avoid this shame! :) Take a look at the lame server report below. It is updated weekly. My thanks to those who donate to the data. http://www.cymru.com/DNS/lame.html Comments, feedback, donated data, and peering sessions are always welcome! Thanks, Rob. -- Rob Thomas http://www.cymru.com ASSERT(coffee != empty);

Public-held Tier2/3 ISPs
by A H 28 Aug '02

28 Aug '02

Hi, I'm currently preparing a small paper on North American service provider economics (educational purposes). I'm missing some Tier2/3 ISPs which have public financial data available. Can anyone give a few names? The paper won't include company names (i.e. company x, company y), and besides I don't expect it to be widely distributed. Thanks for any Help! _________________________________________________________________ Join the worlds largest e-mail service with MSN Hotmail. http://www.hotmail.com

Does your cell phone work in the room? The CDMA time receivers work in the strangest places. The only places I've had no luck: - In the bowels of a big building along the mass tech corridor - when moved to a bad spot inside a fairly steel and concrete-heavy lab at the university of utah (works in other spots in the lab). But aside from that, I've got them working in network closets and labs all over the place. Worth giving a shot if you're really desperate to play. They're not quite as accurate as GPS (~10 microseconds vs. ~2-5 microseconds), but what's a few microseconds compared to sticking an antenna on the roof? (As a frequency standard, they're quite good. But you can't autocorrect for the CDMA propagation delay). -Dave -- work: dga(a)lcs.mit.edu me: dga(a)pobox.com MIT Laboratory for Computer Science http://www.angio.net/ I do not accept unsolicited commercial email.
