There are probably a nudred reasons why a warp would occur.
Starting at your computer and working your way to the server, here are some (?) of the possible elements that would induce warp.
1) Video card is out of texture ram, or is needing to load a new texture into video ram and this could cause a warp to occur.
2) Modem retrain occurs. This would cause some really significant warps in a heated battle.
3) Hard disk soft error occurs during read/write. A disk retry would cause a warp to occur.
4) The phone company has to reroute your call, which causes a modem retrain, see #2 above.
4a) If DSL, the phone company switch needs to alter your allocated bandwidth to make room for some other user trying to get thier bandwidth. This would cause a warp.
4b) Some cable modem user next door decides he needs to download Windows 2000 from the Internet. This would cause your entire block to warp.
5) Your ISP is experiencing saturation of thier connections for a moment. This would cause a warp.
6) Any router between you and HTC experiencing saturation, routing problems, or general mayhem, would cause a warp.
7) All the above would cause warps in any combination, at any time.
8) The other plane you are chasing is experiencing any of 1-6 above would cause warps to appear.
HT's servers have yet to break a sweat. I know what they are capable of,...I built them and they are not even breathing hard at peak times.

Just some thoughts.
