Re: Terrible performance Leicester (LE3)

congestion can sometimes ease off, but is probably due to less people been online for any given reason or perhaps heavy downloaders taking a break.

VM's local network is fragile, 3 20mbit users downloading at full speed will saturate a downstream channel holding 100s of users. On the upstream it requires more users but of course there is only 1 upstream channel. Of course we also have the 50mbit users on the overlay as well.

LE3 is oversubscribed I have little doubt, VM didnt even try to deny it, what I find sad is they dont have the moral to suspend new signups whilst fixing the problem, and twice now I had to tell them they overloaded so can start upgrade work when they claim they normally do it as a matter of course via monitoring. Last time was in early may late april time and the reseg didnt complete until september. I also think multiple reseg's are needed but I expect they will only do one at a time doing the absolute minimum required. This was proven already when the last reseg barely made things work for a month. Given it takes tham half a year to do a reseg they need to ensure there is enough capacity free for 6 months worth of growth after a reseg.
