BGP data during syria blackout

Basically the data is all the BGP updates and withdrawal messages for 2
Syrian networks. 82.137.192.0/18 is the one with the DNS servers for SY.
The format is somewhat self explanatory. Basically it has
timestamps, Type (A=announcement / path change W=withdrawal /lost path)
then the peerAS, that's the Autonomous system that saw this update (on
of bgpmon peering partners). Then the prefix and ASpath. The Aspath is
basically a sequence of AS numbers through which the packet will travel
before it will reach its destination. The left AS is the peer (local)
AS, the most right one is the source AS (the one that owns / originated
the prefix).

One thing to know about BGP and ASpaths is that in general routes with
the shortest ASpath are selected as best paths.

Let's look for example at how AS271 (BCNET - University network here in
BC, Canada) saw the events:

date=1367952365|datetime=2013-05-07
18:46:05|type=A|peerAS=271|prefix=90.153.128.0/17|ASpath=271 577 6453
29386 29256|inet=4|sourceAS=29256|transitAS=29386
date=1367952384|datetime=2013-05-07
18:46:24|type=A|peerAS=271|prefix=90.153.128.0/17|ASpath=271 6327 2914
6453 29386 29256|inet=4|sourceAS=29256|transitAS=29386
date=1367952396|datetime=2013-05-07
18:46:36|type=A|peerAS=271|prefix=90.153.128.0/17|ASpath=271 577 1239
6453 29386 29256|inet=4|sourceAS=29256|transitAS=29386
date=1367952406|datetime=2013-05-07
18:46:46|type=W|peerAS=271|prefix=90.153.128.0/17|ASpath=|inet=4|sourceAS=|transitAS=
date=1368022352|datetime=2013-05-08
14:12:32|type=A|peerAS=271|prefix=90.153.128.0/17|ASpath=271 577 6453
29386 29256|inet=4|sourceAS=29256|transitAS=29386
date=1368022352|datetime=2013-05-08
14:12:32|type=A|peerAS=271|prefix=90.153.128.0/17|ASpath=271 6939 1299
6453 29386 29256|inet=4|sourceAS=29256|transitAS=29386

You can see it changing paths at around 18:46, bounced around for a few
seconds, trying to find alternative paths, before giving up and sending
the withdrawal at 18:46:46.

Then at 14:12:32 it found a new path (syria back online).
