Earlier this month, several users worldwide reported that they were unable to access pirate websites including the Pirate Bay. It was because the internet backbone network of Cogent Communications had blackholed the CloudFlare IP-address of pirate websites
. Less than a week later, CloudFlare is fighting back
. From a report on TorrentFreak: The Pirate Bay and dozens of other pirate sites that were blocked by Cogent's Internet backbone are now accessible again. CloudFlare appears to have moved the sites in question to a new pair of IP-addresses, effectively bypassing Cogent's blackhole. [...] As of yesterday, the sites in question have been assigned the IP-addresses 188.8.131.52 and 184.108.40.206, still grouped together. Most, if not all of the sites, are blocked by court order in the UK so this is presumably done to prevent ISP overblocking of 'regular' CloudFlare subscribers.
