What is incident.io?

incident.io now drafts status page updates with AI while the team edits together.

incident.io's center is Investigations, the agent that posts a root-cause hypothesis when an incident opens. October pushed its skills into coding harnesses and opened Nexus to customers' own tools. November turns to incident communications: the 11-03 release set org-wide guidance for how summaries and updates are written, and the 11-10 release lets a team draft status page updates together, with an AI first draft.

What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

incident.io now drafts status page updates with AI while the team edits together.

◆ Current state

incident.io's center is Investigations, the agent that posts a root-cause hypothesis when an incident opens. October pushed its skills into coding harnesses and opened Nexus to customers' own tools. November turns to incident communications: the 11-03 release set org-wide guidance for how summaries and updates are written, and the 11-10 release lets a team draft status page updates together, with an AI first draft.

◆ Where it's heading

After a month of agent extensibility, the AI is moving into the outward-facing part of an incident: what customers read. The guidance control and the shared drafting fit together, the first setting the tone and the second putting AI drafts in front of the people who approve them.

◆ Prediction

Expect more of the incident write-up flow, such as post-mortems or customer emails, to start from AI drafts governed by the same org-wide guidance.

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
