The 10G Akamai stack at the University is having an affect.

The University turned up routing from the GigaPOP to MICE on its 10G 
link Tuesday around 8pm.  The new paths were also announced to the 
Akamai route collector around that time too.  Akamai started using these 
new paths around 1:30 in the afternoon on Wednesday.  The University's 
10G link peaked a little over 1G around 9:30pm last night.  The 
bottleneck is the 1G link between the CNS 10G switch and the 4500.  It 
was saturated from about 6:30pm to 9:30pm at about 950Mbps.

Some of us are organizing to rectify the situation ASAP. There are some 
workarounds that could help in the very short-term, yet this morning, 
and we are looking to get the new Juniper switches with 10G up-links 
installed ASAP  However, the earliest that can happen it this afternoon, 
as the switches are down in Mankato with Jay.  There is a plan to get 
them up to 511 by mid-afternoon.

Also I'll be watching the links and can modify our announcement to the 
Akamai route collector if necessary. Things are going to be fluid today.

I'll just say that this is the kind of problem I like to see, if you are 
going to have to deal with any problem.  That is the problem of over 
succeeding.
