Provenance Record

Well-structured News piece (Overview / What We Know / What We Don't Know). 581 words, appropriate for the News category (400-1200). Neutral, factual tone throughout with no editorializing or AI self-reference. Timeline is presented clearly and in chronological order.

All 4 source snapshots were read in full from the gzipped local copies under sources/2026-08/github-actions-outage-spans-over-eight-hours-cascading-into-pages-copilot-and-webhook-delivery/ (sha256 of each decompressed file matched the manifest, confirming integrity). (1) source-0.html.gz (The Register, theregister.com) - confirmed the 1522 UTC 'degraded performance' report, the ~20-minute escalation to 'degraded availability', the 1740 UTC mitigation quote and list of affected services (Copilot code review, Copilot coding agent, hosted runners, GitHub Enterprise Importer), the incident-count figures (26 in April, 23 in May, 23 in June, 26 in July, with a July 29 outage), the SVP title for Jakub Oleksy, and the note that GitHub did not respond to The Register's request for comment. (2) source-1.html.gz (githubstatus.com/history.atom, official GitHub status feed) - confirmed the full incident timeline verbatim against status-page entries: 15:22 UTC investigating, 15:41 UTC degraded availability, 17:40 UTC mitigation-and-affected-services quote (verbatim), 23:13 UTC 'invalid jobs'/backlog quote (verbatim opening clause; the source continues '...of affected jobs' which the article quote omits without ellipsis - immaterial truncation, not a misquote), 00:01 UTC 'queues have been drained' quote (verbatim), 00:05/00:06 UTC mitigation-of-Actions-and-Pages status (article attributes the 'Actions and Pages... mitigated' language to 00:06 UTC; the exact phrase appears in the 00:05 UTC entry one minute earlier, with 00:06 UTC being the immediately following 'Monitoring' status change - immaterial one-minute conflation of two adjacent updates describing the same mitigation), 00:59 UTC 'taking longer than expected to recover' quote (verbatim), 02:03 UTC 'stuck in an idle state' quote (verbatim), and 02:04 UTC resolution timestamp (verbatim). (3) source-2.html.gz (mitchellh.com, Mitchell Hashimoto's personal site) - confirmed the April 28, 2026 publication date and both direct quotes verbatim: 'Almost every day has an X' and the full 'is no longer a place for serious work if it just blocks you out for hours per day, every day' passage. Article correctly notes this post predates and is not about the Aug 6 incident specifically. (4) source-3.html.gz (github.blog) - confirmed the article is titled 'GitHub availability report: May 2026', authored by Jakub Oleksy, published June 11, 2026, and contains the quote 'We are making structural changes that permanently remove failure modes' verbatim. No suspicious_patterns were flagged in the manifest for any of the 4 sources; not applicable.

Every specific claim, timestamp, and direct quote in the body traces to and is supported by its cited source. No hallucinated quotes or fabricated specifics found. Two immaterial nuances noted above (a quote truncated one clause short without ellipsis at 23:13 UTC; a mitigation phrase attributed to 00:06 UTC when the exact wording appears one minute earlier at 00:05 UTC) do not change the meaning of any claim and do not rise to the level of a public correction.

High-quality, well-sourced News piece. All four sources were read in full and every claim, timestamp, and quote checks out against them, with only two immaterial nuances noted. The automated warning stems from a source-allowlist gap, not a content defect, so I am approving without a corrections record.
