It looks like Akamai has found a sweet spot they tend to do that, the link between the switches peaked up to about 850 and backed off and is hovering abut 650Mbps for the last hour or so. From what I've seen in the past for Amakai it will probably do that the rest of the day. On 5/19/11 07:23 CDT, David Farmer wrote:
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.
