Huge packet loss while using SL

If I sum it up: I have tested 3 computers in 2 towns and using 2 different major ISPs around here. ALL of them suffer of huge packet loss spikes. Like every 30-60 seconds I get packet loss spikes of 15-50%. During the last week spikes have become worse and worse.

As far as I can tell no other game or program suffer of that in any of the computers I have tested. I seem to get packet loss only when using Second Life.

Are servers overloaded or is routing to europe broken in somewhere?

Keep in mind that regardless of where you try a game it still runs the same route (basicallly) to get to the game servers themselves. You can always try running a "tracert" command from the dos prompt to see all the hops to the game servers. That would at least give you an idea of where the packet loss is occuring. It could just be a really congested router somewhere that is creating the problem for you.

It is very likely some router which is either misconfigured or overloaded.

EDIT: According to Winmtr problem is not in US after all, but somewhere in Sweden in TeliaSoneras network. There one node cause 9% and other 65% packet loss.

EDIT2: Node with 65% packet loss is "s-bb1-pos6-2-0.telia.net" which as far as I can tell is located somewhere in Sweden.

Ok, more tests. Vanguard: SoH seems to route through same node and as far as I can tell it works as expected with no packet loss (tested about 5 mins as SL gets hit by loss spikes every 15-60 seconds).

I did notice and record big packet loss due to timeout latency in one of the USA backbone nodes recently, but put this down the the power outages being suffered. I also find packet loss, again due to timeout latency, whenever LL do 'live' tinkering with the grid, ususally a couple of days prior to sim server restarts. This is mainly because they have to reroute certain network nodes within their network, while they 'tinker', causing bottle necks with the system.

Yesterday I noticed that the more people logged to SL, the worse and the more frequent packet loss spikes became.

Last night (GMT) I saw huge ping rates of 1.5k-10k+ms and time dilations dropping to 0.33% on a lot of sims as I TP'd about. Chat lag was one indicator, voice was very intermitent if working at all, and loggin/logout delays all very sluggish. For someone who hardly notices these issues diring a 'normal' day in SL, I can only imagine how bad it must have been for users with much lower spec systems.....

It only normaly gets this bad, when either LL are tinkering with the sim server code and we are about to get a wave of restarts... or there is another update looming.

Dunno what it is, but I am back in my first conclusion that it is caused by network SL uses. Second Life is not only program I use which is US based and still only it suffers of packet loss.
