  I reboot every friday. Prior to that and any reconfigurations
  we change the dns to point to the machine were squid was initially
  developed , wait until all connections are on the other machine
  and have full access to the main proxie , once reconfigured
  rebooted , the dns is changed back , not one user should
  notice , and if they do , they are not using the correct
  dns or they using the ip , wich is not given out by us.

  Squid's performance is most satisfactory , plus it doubles
  as a tucows mirror. The alternative is paying for a commercial
  product , that works , but takes a lot of time to set up
  and maintain , with the added advantage of "hacking" the
  code to suit your specific needs , and the convenience of
  accessing it without having to walk to the ops room and plug
  in a monitor every time. Taking the performance of linux
  in general , It's a bonus thats it's free. The service
  of linux is the envy of many commercial developers out there.

  Another quick point , is there any settings , kernel configs
  that apply to a .3 sec int delay. Because we have good ping
  response , but a lot of proxie stalls , with no apparent server load.
  I just put it down to packet loss.

  Many regards
  

  Ps. Spread the gospel , register at counter.li.org (Linux user/
      machine count. 53000 so far since nov 7)
