Users encountered elevated error rates and interrupted streaming responses. Other models were not affected.The degradation was caused by an issue with an upstream model provider. GitHub engineers detected the issue through automated monitoring, displayed in-product warnings for the affected models, and coordinated with the provider. Service returned to normal after the provider implemented a mitigation.","summary":null,"severity":"medium","cvss":null,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"GitHub","fixed":[],"affected":"","ecosystem":"vendor"}],"ecosystems":["vendor"],"tags":["ci","git","github","incident","ops","vendor"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"resolved","published_at":"2026-08-31T09:15:48+00:00","first_seen_at":"2026-10-23T19:12:22+00:00","triaged_at":"2026-10-23T21:52:55+00:00","updated_at":"2026-10-23T21:52:55+00:00","category":"vendor","confidence":null,"triage":null,"analyst_status":null,"analyst_note":null,"search":"'-5.2':44C '-5.3':46C '-5.4':49C,51C,54C '-5.6':59C '08':24C '09':27C '2026':33C '31':32C '37':25C '41':28C '7fxts6gmq5gr':15A 'affect':38C,105C 'affected.the':78C 'august':31C 'autom':96C 'caus':81C 'ci':17B 'codex':47C 'coordin':108C 'copilot':11A,35C 'degrad':37C,79C 'detect':92C 'display':98C 'elev':2A,67C 'encount':66C 'engin':91C 'error':5A,68C 'experienc':36C 'famili':60C 'git':18B 'github':1A,14A,16A,19B,34C,90C 'gpt':40C,43C,45C,48C,50C,53C,58C 'implement':119C 'in-product':99C 'inc':13A 'inc-github-7fxts6gmq5gr':12A 'incid':20B 'includ':42C 'interrupt':71C 'issu':84C,94C 'luna':61C 'mini':52C 'mitig':121C 'model':8A,41C,75C,88C,106C 'monitor':97C 'nano':55C 'normal':115C 'op':21B 'openai':7A 'product':101C 'provid':9A,89C,111C,118C 'rate':3A,69C 'respons':73C 'return':113C 'servic':112C 'sever':39C 'sol':62C 'stream':72C 'terra':64C 'upstream':87C 'user':65C 'utc':29C 'vendor':22B 'warn':102C","nicknames":[],"mitigations":[],"who_affected":null,"tier":null,"verified":{},"analyst_revisit_at":null,"first_public_at":"2026-08-31T09:15:48+00:00","kev":null,"cvss_vector":null,"cvss_by":null,"poc_count":0,"sources":[{"source":"statuspage","external_id":"github:7fxts6gmq5gr","url":"https://stspg.io/8trzn5bjrtnn","severity":"medium","published_at":"2026-08-31T09:15:48+00:00","modified_at":"2026-09-03T21:39:35+00:00","first_seen_at":"2026-10-23T19:12:22+00:00","fetched_at":"2026-10-25T13:59:05+00:00","note":null}],"documents":[],"notice":"Free to read at a human pace.
