That&amp;#x27;s the result where if your demand is generated by a Poisson process, and your service has a queue, 80% utilization of the service is where the probability of an infinite queue starts to get really high.

There are tools on monitoring of load all the time, and areas are routibely getting split etc. to improve bandwith, so I think your ISP are basicly amateurs..</text><parent_chain><item><author>rococode</author><text>I&amp;#x27;ve been having major internet issues lately (Seattle area), have had 4 techs come try to figure it out.
