Comcast upgrade backfired, reducing uploads from 20 to 16Mbps until it was fixed.
Jon Brodkin - 3/10/2021, 2:10 PM Some Comcast customers received an unwelcome surprise yesterday morning when their upload speeds were suddenly lowered from 20Mbps to 16Mbps. Comcast was raising download speeds on its "Extreme Pro" tier from 600Mbps to 800Mbps—good news, to be sure—but the plan's relatively paltry 20Mbps upload speeds received a simultaneous 20 percent cut. Customers affected by the change complained to Comcast, and two of them emailed Ars yesterday. When we passed these complaints on to Comcast public relations, a spokesperson initially told us that "there was no change to the upstream speed." But after we pointed out that customers were in fact getting reduced upload speeds, Comcast investigated further and discovered it made a mistake while rolling out download-speed upgrades for some of its plans. "The customers who received the [download] speed increase last night should now be seeing the correct upload speeds in their usage meter," Comcast told Ars last night. "When we pushed the speed increase overnight, there was an issue with how the upload speeds were provisioned, which is why the meter and our internal tools that our care agents use were showing the upload speed of 16Mbps. Once you notified us, we quickly looked into it and everything should be correct now." The fix is rolling out automatically so customers don't have to do anything, Comcast said. "For a period of less than 24 hours, customers would have seen slightly slower upload speeds," Comcast told us. "This issue only impacted customers in our Central markets who received this [download] speed increase from 600Mbps to 800Mbps." Comcast overprovisions speeds so that customers often get a bit more than their advertised plan states. This strategy can reduce user complaints in general, and it means that customers' uploads weren't necessarily cut all the way down to 16Mbps when yesterday's bug hit. Comcast told us that the problem affected users in Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Michigan, Mississippi, South Carolina, and Tennessee. Comcast often makes network changes one region at a time, so we assume customers in other states will get the download-speed increases later on if they haven't already. < - > https://arstechnica.com/information-technology/2021/03/comcast-scrambled-to-fix-mistake-that-cut-some-users-upload-speeds-by-20/ -- Iw mailing list [email protected] http://sticklist.org/mailman/listinfo/iw_sticklist.org
