Note that the problems that hit SprintLink today also effected AlterNet
- we are not 100% sure yet (still comparing timestamps in logs), but it
looks like routing problems hit SprintLink, SprintLink route flaps then
got to AlterNet, and parts of AlterNet also tipped over (we had several
routers near MAE-East hit 100% cpu trying to deal with route flaps).

CIDRize or die.

I intend to spend quite some time this evening/night trying to see what
additional routes AlterNet can squeeze out of the routing tables; I
strongly suggest that oter service providers do the same.
