marcan writes "Comcast users are reporting 'connection reset' errors while loading Google. The problem seems to have been coming and going over the past few days, and often disappears only to return a few minutes later. Apparently the problem only affects some of Google's IPs and services. Analysis of the PCAP packet dumps reveals several injected fake RSTs, which are very similar to the ones seen coming from the Great Firewall of China [PDF]. Did Google somehow get caught up in one of Comcast's blacklists, or are the heuristics flagging Google as a file-sharer due to the heavy traffic?"
