Dear ICP Developers,

We want to inform you about an ongoing issue affecting our primary domain for hosting user canisters, icp0.io, which has been listed in the Spamhaus Domain Blocklist (DBL). While we are actively working to resolve this, there may be temporary side effects:

  • Social media posts featuring links to icp0.io may be flagged as spam or restricted.
  • Some corporate or personal internet filters may block connections to icp0.io or display warnings.

We have provided all the requested information to the Spamhaus team and were hopeful this issue would be resolved before the weekend. Unfortunately, the matter remains unresolved. :disappointed:

We will keep you updated as the situation evolves and are evaluating further actions depending on the outcome.

Thank you for your understanding and patience as we work through this.

Best regards,
Infrastructure Security Team

Update:

  • We still have an active support case open and waiting for Spamhaus, but the matter remains unresolved.
  • We are also monitoring other blocklists, but have not detected any other blocks for the icp0.io domain.

Thanks,
