Mirrors

  • taurine (90 Mbps)
  • citric-acid (250 Mbps)
  • natural-flavours (200 Mbps)
  • artificial-flavours (200 Mbps)
  • perpugilliam (90 Mbps)

We also use mirror.cs to mirror on-campus.

QoS

We are currently looking at implementing QoS on the host end. IST's QoS plan is documented here: http://ist.uwaterloo.ca/~dkeenan/docs/QoS-plan-draft.html. IST recommends using "IP Precendence 1, PHB CS1, DSCP 8, CoS 1". The ports we want to limit are 80 (HTTP) and 6900-6999 (BitTorrent).
