What is Grafana Loki?

Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.

RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

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.

6.3

Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.

◆ Current state

Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

◆ Where it's heading

Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.

◆ Prediction

Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.

ANALYTICS
2.5

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.
