Surely (yes I am calling you Shirley :p: ) the server bottlenecks would have stopped the backbones getting saturated unless of course the requests themselves are the cause? Perhaps you can explain more..please.. :)

Does anyone know where the bottleneck was, i.e. did anyone so a few tracerts last night. Maybe people across the world downloading iOS6 saturated a couple of peering links?

I was, sorry if it was a bit vague.

I didn't say anything about iOS6, I only said the issue was more widespread than "very close". As for jumps - the most critical jumps don't show up on traceroutes. And lest not forget, Moscow and New York are "only" 3 jumps outside of VM's network as well.

While I little care about iOS6 or its effects on the internet, I think you've got server bottlenecks and backbones the wrong way round. Servers have far more capacity than the switches they are connected to, and those switches have far more capacity than the routers or backbones they are in turn connected to.

For example one datacentre may have 1000 servers with 1-4Gbps capacity each, hooked up to 64 10Gbps switches hooked up to 40Gbps of internet.

Looks like it's doing it again tonight.

:rolleyes: This is getting ridiculous... One night, sure I can live with that, but two in a row is just plain unacceptable. my speeds are decreasing as the ping on that chart gets higher. 55ms right now with a speed of 90 down 8.87 up...

Same here again so that discounts iOS6 downloads but points towards something being altered/started at the exact same time

Thanks for the more detailed explanation :tu:

looks to me like the graphs are normalizing already so I am guessing VM must have changed the routing around what ever is causing the issue?

I had the same high Minimum Latency last night it seems.

any idea what causes that? been an ongoing issue over the last week

I got the 6-8pm spike but I also got a load of US congestion around it followed by ongoing congestion to now till nearly 2am, so looks like my new US channel didnt work well for long, a torrenter has followed me onto the channel. Seems the spike made others channel hop to try and get round it. :(

The routing fix seams to be holding this time. The default gateways even back to normal..Might still be Knacked else were... but normal service no spike yet... for me..

This is what happens when you don't pay attention to your monitor for a few days!
Gone from 5 downstream to 6 downstream, and from 1 upstream, to 2 upstream. Stats and graphs below.

(No idea what happened here, judging by the comments on this thread, looks like a TBB issue.)

(Virgin Media did well with not making me notice until after a few days. Had no idea the internet had been down, usually I do!)

Haven't really noticed a difference in browsing or anything, though.

@ Neo-Tech
You should be ready for 60/6 soon then.
let us know how it goes... might want to upgrade..
