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 38 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.

statuswall is independent and is not affiliated with, sponsored by or endorsed by any company named here. Company and product names are used only to identify whose public information is being referred to. The information is provided as is, for general reference, with no guarantee that it is complete, current or free of error; it is not security, legal or purchasing advice. Where this page and an official source differ, the official source is right.
