Outages and root causes.

Two years of public outages, and what each company said caused them. Every entry links to the company's own write-up; nothing here is our speculation.

CircleCI
Jul 2, 2026
Pipelines failing to start and UI inaccessible
Some customers could not start pipelines, log in or load the CircleCI UI for about an hour and a half.
Root cause, as stated by CircleCI
An internal data-deletion job overlapped with a burst of customer project deletions and overloaded a data service, and missing timeouts let slow responses exhaust API workers.

Who publishes root causes

Write-ups posted on status pages, last two years

Public information only

Everything on this page was already published by the companies themselves or by public bodies. statuswall gathers it in one place, links every item to its original, and adds nothing from private or leaked sources.

Sources

Official status pages: incident titles, severity, times and the link to each published root-cause analysis, exactly as each company posted them
Company engineering blogs and incident reports: the basis for the notable-outage summaries, each linked from its card

How fresh it is

Incidents and RCA links: re-read from every status page about once an hour; last run 2 min ago
Notable-outage summaries: written by hand and last checked against their sources on Nov 10, 2026

Titles, severity and times are as published on each company's status page. "Published RCA" means the company posted a postmortem on that incident's official page; we link to it and do not reproduce it. Many companies publish root causes on a blog instead, or not at all, so the absence of a link is not evidence that no analysis exists. Severity grading differs between companies and is not comparable across them. This is not a complete record of every outage.
