Anybody watching the bgp routing table.. I see about 5,000 less routes than
usual. Anybody know a good pointer..
(im just getting bored waiting for us to run out of fuel)

I would assume this is the result of the blackouts taking down entire autonomous systems.

I'm seeing a decrease of 3510 prefixes. There is a bit of churn,
though things are reasonably calm overall.
Total prefix count:

Prefix delta:
<http://www.cymru.com/BGP/deltapref.html>
Other bits of critical infrastructure seem to be unimpacted.
Root server response:
<http://www.cymru.com/DNS/dns.html>
com/net gTLD server response:
<http://www.cymru.com/DNS/gtlddns-cn.html>
Interestingly enough, some of the error conditions in the global
table have decreased.
Prefixes with inconsistent-as:

Others have not:
Bogus ASN leakage:

Hang in there! I hope the power is restored to everyone soon. If
there is anything I or Team Cymru can do to assist, don't hesitate
to ping on us.
Thanks,

I saw a drop of 2655 prefixes and 425 ASN.
Reminds me of the drop several days _after_ 9/11,
when the generators ran out of power. As a guess, these must
be enterprise ASN without backup power.

Here's some of what I've seen at this point:

* Current Based on my Snapshot @9P MDT 8.14.2003
Note: This data came from an Arbor system on a regional network. There's
a bunch more qualitative and quantitative data I'll munge through when I get
a chance, could be interesting. If folks are looking for anything in particular
let me know, I can likely dig it up...

I failed to consider that today's average has been skewed by the outage
data being factored for the last 10 hours or so towards the "Daily Average".
I looked at yesterday's daily average which was 122855, just over 800
more prefixes.
Current v. Average: 98.73% (1554 prefixes)
So comparing yesterday's average to today's current I get closer
to the value Rob and others posted:
Current v. Yesterday's Average: 98.06% (2380 prefixes)
