Isn't there something in RFC 1149 or RFC 2549 about this? Maybe another update to these RFC will be required.

Does anyone have a good definition of packet loss? If so, please send me the appropriate verbiage. I cannot seem to articulate a strict definition. Your assistance is appreciated.

Hi Bandy! I also just recently received this over the wire. Perhaps it's related? --------------------------------------------------------------------- --------------------------------------------------------------------- NEW YORK (Reuters). In an expected and long-awaited move today, the gay and lesbian community officialy excommunicated Reid Fishler (aka "redbird"), declaring him _vitandi_ status, and ordered never to speak to another homosexual again. "This is a great day for our people," exclaimed G&L spokesperson Erik Katenoub, in a press conference this afternoon. "The separation of reid from Our Community has been long in the works, and we hope that this will vindicate us, and start us on the path to social recovery." This is the second official excommunication of a gay person in history, only second to Linus Torvalds' dramatic separation in 1994. Fishler was unavailable for comment. ### --------------------------------------------------------------------- --------------------------------------------------------------------- I'm really sorry that I can't comment further, however; I'm too busy flapping the shit out of mae east with my cool router: Dec 14 02:00:50.691: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:01:36.723: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:02:30.380: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:03:07.568: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:04:33.552: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:05:28.009: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:06:08.133: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:06:46.548: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:12:14.333: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:12:54.246: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:14:07.310: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:14:47.306: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:16:13.747: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:18:41.380: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:22:30.086: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:23:13.950: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:24:21.174: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:25:16.947: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:26:13.183: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:26:58.635: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Dec 14 02:28:03.864: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Down - Peer closed the session Dec 14 02:28:46.860: %BGP-5-ADJCHANGE: neighbor 192.41.177.196 Up Only a few more reboots and i think i might have it fixed!

This is not true. I am glad there is such great information out there. Lightning is experiencing an outage, and will be moving out of Abovenet, yes. Thats all I have to say about this now, but you certainly do not have the correct story. If your so sure of your information, why don't you come out from behind your hotmail address?

Lightning and nacamar down?
by Bandy Rush 13 Dec '00

13 Dec '00

Does anyone know what is happening with Lightning and nacamar at MAE-East? I am told that AboveNet shut Lightning down for non-payment, taking down their MAE-East FDDI and ATM connections, and that Nacamar had their gear in Lightning's AboveNet space? Is this true? I know the Gigabell bankruptcy probably put Lightning in a hard spot. Hoping to see them stay up for their IRC servers and freesoftware.com's sakes.
