Comment (by cypherpunks):

 i see these logs a lot on a 3G mobile broadband connection with an
 internet telco that heavily tampers with connections to tor

 but how they do it i dont know

 what tools can i use to try and gather evidence of this tampering?

 is this flooding multiple TCP duplicate ACKS?

 is this more common on a tor alpha or RC version ?

 i can promise you that i never see this at local cafes and connections to
 tor are fine
