I'm getting a servfail when attempting to resolve their domain, according to DomainTools[1] the IP for the site was 185.215.113.235 announced from AS42229.

The ASN was mentioned in the article as being listed by Spamhaus ASN Droplist but wasn't mentioned earlier as one of the targeted ASNs.

Edit: reviewed the ASN more and it is the Ebony Horizon mentioned in the article, and it is only peered to BitCanal's primary AS197426, which is subsequently being de-peered, so I'd say that is the main reason bitcanal.com is down :) 1: http://whois.domaintools.com/bitcanal.com

I timeout on getting an IP, but I noticed Opera/Chrome already flagged the url as unsafe despite the dns fail.
