Hey Willy, Thanks for taking the time to respond.
It jumps from about 300-500ms to 3000-4000ms. There's a few other sites that have the same variance on the same server. Typically 10x jumps in latency. There's no rhyme or reason I can find. Here's a fancy pants graph. http://screencast.com/t/mcZ4wRQaBTt Here's also an excerpt from my log from today, I filtered only request > 1000ms. These are requests from the same graph above. I don't even see the highest response times that are listed on that graph (one peaking above 4000ms).
