ANALYTICS
Velocity2.5

updown.io sends domain-expiry alerts to every channel and moves French SMS alerts to a UK number.

◆Current state
On 8 November updown.io moved SMS alerts sent from its French number to a UK number after the French regulator reserved mobile numbers for person-to-person messages. The same update routes domain expiration alerts through every notification channel with a new webhook event, adds dashboard warnings for malformed HTTP/2 headers, errors after a 2xx and charset mismatches, and exposes certificate details in the API. September brought a detailed check page with multi-year heatmaps and SLA history.
◆Where it's heading
updown.io keeps widening what a single check reports, from heatmaps and SLA history to certificate and domain data, while staying a small, steady shipper. Alerts now reach the channels teams already use rather than email alone.
◆Prediction
Expect more domain and certificate signals exposed through the API and webhooks, extending the domain-expiration event added here.

    🛑 Closed port monitoring

    Closed TCP port monitoring lets teams verify that firewall rules are actually blocking ports — a security-posture use case that uptime monitoring tools rarely cover, extending updown beyond availability into basic network hygiene.

    String match with pulse checks

    String matching in pulse check bodies lets updown verify that a periodic task sent meaningful content in its heartbeat, not just that it arrived — a correctness check for cron job monitoring beyond simple liveness.

    New monitoring location: Cape Town, South Africa

    Cape Town (South Africa) monitoring node adds an African presence point — geographic expansion with the usual IP-filtering caveat for accounts that restrict locations.
