Vercel
Oct 20, 2025
Service disruption during AWS us-east-1 outage
Static serving failed for up to about a fifth of traffic for a short period and functions pinned to the us-east-1 region failed for about two and a half hours, while deployments, dashboard, APIs and runtime logs were disrupted for much longer, with full recovery almost a day later.
Root cause, as stated by Vercel
The AWS us-east-1 outage triggered a cascading failure in Vercel's regional cache service and, via a feature-flag provider outage, resource exhaustion in its primary control-plane cluster.

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 3 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.
