Official response from Quad9. Since storj.io seems to be an open cesspool, still seems like iXsystems needs to move to another provider.
Hello,
Please accept our apologies for the delayed response/action.
Earlier this year, we informed Storj.io that all that was needed for Quad9 to set a permanent exclusion for this FQDN was to add a “Report Abuse” link to the footer of their website, which is a common practice for CDNs, and would only serve to help Storj.io by encouraging netizens to report any malicious files to them directly, as opposed to reporting them to threat lists.
Quad9 initially tried getting this removed as a false positive with one of our threat intelligence partners, but this kept filtering down from various upstream threat feeds [0], and it became a game of whack-a-mole. We had no idea this was going to be a multi-week episode.
We’ve added a permanent exclusion for link.storjshare.io, despite Storj.io not complying with our requirement.
We apologize for any inconvenience caused.
