6 months ago, Rogers admitted that its "traffic management equipment that can interfere with World of Warcraft .. We have determined that the problem occurs only when our customers are simultaneously using peer-to-peer file sharing applications and running the game" - see "Rogers [Canada] Admits its P2P Traffic Management Impacts Interactive Gaming" - here.
Now, the CRTC has instructed Rogers to fix the problem. In a letter that was sent on Friday to Rogers, (here, from DSPreports.com), John Traversy, Executive Director, Telecommunications says: "Commission staff notes that in its report entitled World of Warcraft Testing, dated 25 July 2011, Rogers indicated that it had implemented a “whitelisting” solution to resolve issues related to misclassification of this specific game. Based on information provided by Rogers’ 2 September 2011 letter, as noted above, Commission staff considers that Rogers’ ITMPs could potentially continue to misclassify time-sensitive traffic such as other online games and therefore this could be affecting those games. Commission staff considers that Rogers should address and resolve this misclassification problem As a result, Commission staff requests that Rogers file a plan for resolving the possibility of misclassification of other interactive game traffic, by 27 September 2011, that includes specific steps and timelines for each step".
