Marc,
We're running a transparent ProxySG from BlueCoat. Using basically the def=
ault settings, we are seeing about an 8% savings. Unfortunately, sites lik=
e YouTube are very hard to cache. BlueCoat has provided us a CPL script th=
at they say some of their ISP customers are using to cache YouTube and the =
like, but we haven't implemented it yet. I would imagine we will see a dra=
matic increase in savings when we do, since currently about 70% of our inbo=
und traffic is streaming media.

Anyone have a content cache running? Does it help if you're caching all the=
fixed elements of from these Web 2.0-type pages?
I'm imagining a box running Squid set up as a transparent proxy with an SSD=
to hold the cache.

We just had a recap discussion on this at our general staff meeting. Yes,
we hit the ceiling on bandwidth management and had to do an emergency
replace on our device (PacketShaper). There was a project already started
to replace it, but a sudden uptick of problems caused it to get
"accelerated". We went with a new BlueCoat box and so far things are
running smoothly. Since replacement the peak has grown nearly a hundred
megs. About 70% of our bandwidth is streaming media and social
networking. We are also already out of the bandwidth bracket we purchased
a while back.
Just curious.. Does anyone else see a large portion of their high request
counts come from NeoPets? That took us by surprise.
