What is OpenObserve?
OpenObserve 1.2.0-rc2 is a long fix list that closes a cross-tenant write gap.
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.
What is updown.io?
updown.io sends domain-expiry alerts to every channel and moves French SMS alerts to a UK number.
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.

OpenObserve
5.0ANALYTICS
OpenObserve 1.2.0-rc2 is a long fix list that closes a cross-tenant write gap.
◆ Current state
OpenObserve opened its 1.2 cycle with rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. rc2 is a large batch of fixes across the new surfaces, including blocking cross-tenant writes through function updates and remote destinations, scoping service graphs and alert lists to what a user may read, and polish for an On-Call module now tagged beta. Fleet, RUM, Kubernetes and synthetics views also got fixes.
◆ Where it's heading
The 1.2 cycle is wider than metrics: rc2's fixes reveal on-call scheduling, fleet management, RUM, synthetics and incident root-cause features heading into the release. Several fixes tighten tenant and permission boundaries, which suggests multi-tenant and enterprise deployments are a priority before 1.2 goes stable.
◆ Prediction
Expect one more release candidate or a 1.2.0 stable soon, followed by 1.2.x backport patches as the 1.1 line had.
updown.io
2.5ANALYTICS
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.
