San Francisco – AT&T’s (NYSE: T) network has seen upload speeds
for iPhone users in a number of cities plummet in recent days, in some cases
below 100 Kbps, Wired.com reported.
Reports of degraded upload speeds began on
Saturday.
Speed test data from 3 million iPhones provided by Ookla shows that
in Seattle, average iPhone upload speeds fell from 525 Kbps on Friday, to 97,
131 and 101 on Saturday, Sunday and Monday, respectively.
Similar drops in
speed were seen in Baltimore; Boston; Cincinnati; Cleveland; Columbus, Ohio;
Denver; Des Moines, Iowa; Detroit; Fairfax, Virginia; Houston; Kansas City,
Missouri; Las Vegas; New York; Orlando, Florida; Phoenix; St. Paul, Minnesota;
Salt Lake City; and Washington, D.C.
AT&T recently reworked its data plans
for iPhone and iPad users.
A spokesman for the company told Wired.com that
"the company will explain the situation soon."
Update: An AT&T spokesperson emailed this statement to DMW:
"AT&T and Alcatel-Lucent jointly identified a software defect — triggered under certain conditions – that impacted uplink performance for Laptop Connect and smartphone customers using 3G HSUPA-capable wireless devices in markets with Alcatel-Lucent equipment. This impacts less than two percent of our wireless customer base.
"While Alcatel-Lucent develops the appropriate software fix, we are providing normal 3G uplink speeds and consistent performance for affected customers with HSUPA-capable devices."
