Is something funny happening with them lately or is it normal to see 45Mbps of UDP traffic between akamai servers (45Mps peak, average for the past 24 hours is around 15Mbps. Prior to that it wasn't enough to show up in our graphs). More information: Our akamai farm is the one recieving all of the data - its coming into our various akamai hosts on port 1455. I've never looked at this traffic before so I don't know if this is normal or not. I understand that the servers have to talk to each other to distribute content but why UDP and why consume so much bandwidth? Chris
Minor correction... Up until around 10am today it was at an average of 2Mbps not 15Mbps. It rose to 20Mbps by 11am, and then hit 45Mbps by 3:30. Its been dropping since then (its at around 30Mbps now). Anyway, is the some sort of normal behaviour for them? Chris Rapier wrote:

Our Akimai's are doing a bit of traffic in the last 6 hours as well, the overnight shift noticed and logged it. I've attached a mrtg graph that is showing the whole thing (green to our farm, blue is from). -- Simon Lyall. | Newsmaster | Work: simon.lyall@ihug.co.nz Senior Network/System Admin | Postmaster | Home: simon@darkmere.gen.nz ihug, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz
Our graph looks almost exactly like that. Not the same magnitude but the same shape. Same shape and if I was concious enough to work out the time difference that might tell us more. Dunno, the UDP traffic from server to server almost makes it seem like something less than normal. TCP I could imagine but UDP? Maybe there was some large streaming media event? heh. maybe they were distributing the roskiled goth festival in norway... :) Simon Lyall wrote:

If they're paying you by the megabit, is anyone complaining? :) -C On Sun, Jul 01, 2001 at 05:41:17PM -0400, Chris Rapier wrote:

As I said, the shape out our traffic looked exactly the same. I'm really just curious as to what happend at this point. I'm not in a position to actually contact Akamai myself as I'm not associated witht eh production network. Maybe our production manager will... Here is the graphs from the 29th. Simon Lyall wrote:
