{"id":"INC-polymarket-cmux3mzg504gi1bqs9gvju2ch","kind":"incident","aliases":[],"related":[],"title":"Polymarket: Scheduled CLOB maintenance","description":"Type: Maintenance\n    Duration: 44 minutes\n\n    Affected Components: Predictions Trading API (CLOB)\n    Oct 8, 04:44:23 GMT+0 - Completed - Maintenance has completed successfully. Oct 8, 04:00:01 GMT+0 - Identified - Maintenance is now in progress Oct 6, 19:56:15 GMT+0 - Identified - A scheduled CLOB release requires a brief restart, with downtime of up to \\~10 minutes. Order placement, cancels, and fills may be temporarily unavailable.  \n  \nUpdate to the live-sports order taker delay implementation (orders that return status \"delayed\"). Before: Held orders were released together at the top of each second. Taker's actual hold was anywhere from 0 to 1s depending on when in the second the order was sent. After: Each held order is released exactly 1s (the market's seconds\\_delay) after the engine receive it. Why: Align with standard delay practices thereby making the hold consistent for all takers. This will also allow fills to arrive as a steady stream instead of a burst at the top of each second. Scope: this only applies to the live-sports seconds\\_delay hold. The taker delay amount itself is unchanged (orders are still held for seconds\\_delay and still return \"delayed\"), and the crypto taker delay is not affected at all.","summary":null,"severity":"unknown","cvss":null,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"Polymarket","fixed":[],"affected":"","ecosystem":"vendor"}],"ecosystems":["vendor"],"tags":["incident","ops","polymarket","vendor"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"open","published_at":"2026-10-08T04:00:00+00:00","first_seen_at":"2026-11-08T17:00:42+00:00","triaged_at":"2026-11-08T17:01:15+00:00","updated_at":"2026-11-08T17:01:15+00:00","category":"vendor","confidence":null,"triage":null,"analyst_status":null,"analyst_note":null,"search":"'+0':31C,43C,56C '0':116C '00':40C '01':41C '04':27C,39C '10':71C '15':54C '19':52C '1s':118C,136C '23':29C '44':17C,28C '56':53C '6':51C '8':26C,38C 'actual':111C 'affect':19C,219C 'align':148C 'allow':164C 'also':163C 'amount':197C 'anywher':114C 'api':23C 'appli':185C 'arriv':167C 'brief':64C 'burst':175C 'cancel':75C 'clob':3A,24C,60C 'cmux3mzg504gi1bqs9gvju2ch':8A 'complet':32C,35C 'compon':20C 'consist':157C 'crypto':214C 'delay':90C,96C,141C,151C,192C,196C,207C,211C,216C 'depend':119C 'downtim':67C 'durat':16C 'engin':144C 'exact':135C 'fill':77C,165C 'gmt':30C,42C,55C 'held':98C,131C,204C 'hold':112C,156C,193C 'identifi':44C,57C 'implement':91C 'inc':6A 'inc-polymarket-cmux3mzg504gi1bqs9gvju2ch':5A 'incid':10B 'instead':172C 'live':86C,189C 'live-sport':85C,188C 'mainten':4A,15C,33C,45C 'make':154C 'market':138C 'may':78C 'minut':18C,72C 'oct':25C,37C,50C 'op':11B 'order':73C,88C,92C,99C,126C,132C,201C 'placement':74C 'polymarket':1A,7A,9A,12B 'practic':152C 'predict':21C 'progress':49C 'receiv':145C 'releas':61C,101C,134C 'requir':62C 'restart':65C 'return':94C,210C 'schedul':2A,59C 'scope':182C 'second':108C,124C,140C,181C,191C,206C 'sent':128C 'sport':87C,190C 'standard':150C 'status':95C 'steadi':170C 'still':203C,209C 'stream':171C 'success':36C 'taker':89C,109C,160C,195C,215C 'temporarili':80C 'therebi':153C 'togeth':102C 'top':105C,178C 'trade':22C 'type':14C 'unavail':81C 'unchang':200C 'updat':82C 'vendor':13B","nicknames":[],"mitigations":[],"who_affected":null,"tier":null,"verified":{},"analyst_revisit_at":null,"fix_status":null,"audience":null,"plain_action":null,"pkeys":["polymarket"],"ptokens":["polymarket"],"labels":["incident","ops","polymarket","unknown","vendor"],"campaign_type":null,"search_a":"'clob':3A 'cmux3mzg504gi1bqs9gvju2ch':8A 'inc':6A 'inc-polymarket-cmux3mzg504gi1bqs9gvju2ch':5A 'mainten':4A 'polymarket':1A,7A,9A 'schedul':2A","search_b":"'incid':10B 'op':11B 'polymarket':12B 'vendor':13B","search_c":"'+0':31C,43C,56C '0':116C '00':40C '01':41C '04':27C,39C '10':71C '15':54C '19':52C '1s':118C,136C '23':29C '44':17C,28C '56':53C '6':51C '8':26C,38C 'actual':111C 'affect':19C,219C 'align':148C 'allow':164C 'also':163C 'amount':197C 'anywher':114C 'api':23C 'appli':185C 'arriv':167C 'brief':64C 'burst':175C 'cancel':75C 'clob':24C,60C 'complet':32C,35C 'compon':20C 'consist':157C 'crypto':214C 'delay':90C,96C,141C,151C,192C,196C,207C,211C,216C 'depend':119C 'downtim':67C 'durat':16C 'engin':144C 'exact':135C 'fill':77C,165C 'gmt':30C,42C,55C 'held':98C,131C,204C 'hold':112C,156C,193C 'identifi':44C,57C 'implement':91C 'instead':172C 'live':86C,189C 'live-sport':85C,188C 'mainten':15C,33C,45C 'make':154C 'market':138C 'may':78C 'minut':18C,72C 'oct':25C,37C,50C 'order':73C,88C,92C,99C,126C,132C,201C 'placement':74C 'practic':152C 'predict':21C 'progress':49C 'receiv':145C 'releas':61C,101C,134C 'requir':62C 'restart':65C 'return':94C,210C 'schedul':59C 'scope':182C 'second':108C,124C,140C,181C,191C,206C 'sent':128C 'sport':87C,190C 'standard':150C 'status':95C 'steadi':170C 'still':203C,209C 'stream':171C 'success':36C 'taker':89C,109C,160C,195C,215C 'temporarili':80C 'therebi':153C 'togeth':102C 'top':105C,178C 'trade':22C 'type':14C 'unavail':81C 'unchang':200C 'updat':82C","cause_entry":null,"cause_path":null,"disclosures_checked_at":null,"first_public_at":"2026-10-08T04:00:00+00:00","kev":null,"cvss_vector":null,"cvss_by":null,"poc_count":0,"sources":[{"source":"statuspage","external_id":"polymarket:cmux3mzg504gi1bqs9gvju2ch","url":"https://status.polymarket.com/maintenance/cmux3mzg504gi1bqs9gvju2ch","severity":null,"published_at":"2026-10-08T04:00:00+00:00","modified_at":"2026-10-08T04:00:00+00:00","first_seen_at":"2026-11-08T17:00:42+00:00","fetched_at":"2026-11-09T01:49:38+00:00","note":null}],"documents":[],"disclosures":[],"exploit_sources":[],"notice":"Free to read, with fair use of about 60 pages a minute.
