I have an AT&T U-Verse “Internet Pro” DSL account. In the middle of June (near the 13th) my latency suddenly improved by 10ms.

Then around the 19th of June (2014) my upstream bandwidth jumped from around 1 Mb/s to around 1.4 Mb/s:

AT&T doesn’t advertise or make any promises about their upstream bandwidth, but these are welcome changes (especially the 40% boost in upstream bandwidth). My downstream bandwidth stayed just above the advertised 3 Mb/s rate.

I don’t know if this was due to a piece of equipment near my home getting upgraded, or the result of a policy change to upgrade the “Internet Pro” account, but I’ll take it!
Anybody else see a similar boost? Or have a negative counter example?
