Blocklist monitoring and a full Report tab for every check
Two things landed this week. A new Blocklist monitor that checks whether your domain or sending IPs appear on the major email blocklists, and a fully fleshed-out Report tab for every other check type. The "ships in a future sub-PR" placeholders are gone.
What's live
- Blocklist monitor — Spamhaus ZEN, Barracuda Reputation, SORBS, SpamCop, URIBL and SURBL all queried in parallel every six hours. Listings surface in a dedicated Report with the exact zone that flagged you, what was queried (an IP or a domain), and the response code the blocklist returned. Most DNSBLs encode the listing reason in that response code, so the report tells you not just "you are listed" but "here is why".
- Per-check Report tabs — SSL, DNS, Domain expiry, Security headers, Broken links and Robots/sitemap now each open into a Report tailored to the check. Letter grades for headers. Drift detection with the previous fingerprint inline for DNS. Side-by-side reachability for robots.txt and sitemap.xml. Cert chain rendered as cards. Broken-links table with clickable URLs and status codes.
- Settings tabs on every check — read-only summaries of what each monitor is configured to do, including the cadence, scope, thresholds and baselines. Configurable forms for these settings land in later sub-PRs.
What changed for you
If you had monitors set up on anything other than Uptime, they were collecting data already but the Report tab was a stub. That changes today. Open any SSL, DNS, Domain, Headers, Links, Robots or Blocklist monitor and you see what the probe actually saw — not a placeholder telling you the data is on its way.
