RE: AS 2828

Hi,

For those who may be interested, you can see how this outage was perceived by 
routeviews' peers at LINX, using Rcat at http://rcat.rd.francetelecom.com/


Set the following options: 

starting date: 2008-02-26 11:30:00
ending date: 2008-02-26 11:40:00
time zone value: Etc/GMT-6
logical query: ori2828


It's event: RV_LINX_2008_02_66828


It shows that the different routeviews' eBGP peers at LINX have announced to 
the trace collector their path to join AS2828 had become unavailable at about 
11:28.

More precisely, it shows (when displaying the path exploration* undergone by 
the eBGP routers connected at LINX) that prefixes 205.159.169.0/24 and 
63.244.0.0/16 (originated by XO) were unreachable between 11:29 and 11:47. 

What is more, it also shows that prefixes from 15 ASs behind XO (mostly 
customers) were also impacted by the outage (some only switched to another path 
but some also experienced unreachability between 11:29 and 11:47)

Finally it shows that at 11:47 all the peers at LINX reconverged to the path 
they were using before the outage.


It can also be noticed that Rcat had indeed identified AS2828 as the originator 
of this outage, which agrees with the core router failure claimed by XO (as 
explained at [EMAIL PROTECTED] )

I seem to have lost connectivity to AS 2828/XO communications. I can't get 
through to anyone on the BGP team at XO either. Anyone else experiencing this? 
Reply just to me, don't need to hold up thread time.
