Has AT&T Wireless data congestion been self-inflicted?
Note: if you don't want to read all the list messages the short summary is: >8 second pings times! What's more the effect was bymodal: either ping times under 200 ms, or over 5 seconds.
It appears AT&T Wireless has configured their RNC buffers so there is no packet loss, i.e. with buffers capable of holding more than ten seconds of data. Zero packet loss may sound impressive to a telephone guy, but it causes TCP congestion collapse and thus doesn't work for the mobile Internet!
