Pirate Bay Overblocking Hits EZTV Due to Shared Cloudflare IP Address

The Pirate Bay is arguably the most widely blocked website on the Internet. ISPs from all over the world have been ordered to prevent users from accessing the torrent site.

This is also the case in the Netherlands. While the issue remains pending at the Supreme Court, ISPs including Ziggo are already required to prevent users from accessing the popular torrent site.

A court ruling of 2017 required Ziggo to block both domain names and IP-addresses of The Pirate Bay and its many proxies. The list of blocked domains has grown to hundreds in recent years and the Dutch blocklist is regularly updated with new domains and IP-addresses by anti-piracy group BREIN.

Thus far, this hasn’t caused any trouble but earlier this month several torrent users noticed that Ziggo’s Pirate Bay blockade had carried over to EZTV.io, another popular torrent site. While EZTV also provides access to infringing content, it’s not covered by the court order. 

Still, EZTV users were welcomed by the following message from Ziggo when they tried to access the site.

As it turns out, both EZTV and The Pirate Bay use Cloudflare and the CDN company decided to put both sites on the same IP-address. As a result, Ziggo’s filters also blocked access to EZTV, which is a classic example of overblocking. 

Ziggo confirmed the error to local news site Tweakers but said that there was little it could do without an update from BREIN. 

“Despite the fact that Ziggo has repeatedly pointed out these these types of risks, the court did not sufficiently account for these types of complications. This means that even if we see or are reminded that a website is being incorrectly blocked, Ziggo is obliged to uphold the blockade, until further notice from Brein,” Ziggo noted.

The ISP said that it informed BREIN about the issue early July, but the list wasn’t immediately updated. This meant that EZTV remained blocked for at least a week. The torrent site was eventually unblocked after BREIN asked Cloudflare to put ETZV on a separate IP-address.

BREIN director Tim Kuik admits that the overblocking took place but doesn’t known why Cloudflare put the sites on the same IP-address. 

“I have no idea why EZTV became available at that IP address. Just like The Pirate Bay, they use Cloudflare and someone apparently thought it was a good idea,” Kuik told Tweakers

While BREIN helped to get EZTV unblocked again, Kuik stresses that the torrent site is illegal as well. The anti-piracy group summoned EZTV to stop its infringing activity and plans to have it blocked in the future as well, once the Pirate Bay case is finalized at the Supreme Court.

Interestingly, this isn’t the first time that shared Cloudflare IP-addresses has resulted on overblocking. Two years go, dozens of pirate sites were mistakenly blocked by Internet backbone provider Cogent, following a court order. Cloudflare eventually resolved the matter by putting the sites on separate IP-addresses.

At the time, Cloudflare’s General Counsel Doug Kramer told TorrentFreak that it’s important for his company to understand how different blocks operate around the world, so  it can limit coleteral damage. However, that clearly didn’t work in EZTV’s case.
