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 outages () isotf org )


Best

You might want to check the thread at outages () isotf org,

But everything looks a lot better on keynote then it did a few hours ago.

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.
