Sep 2, 04:35:36 GMT+0 - Identified - We are currently in cancel-only mode. We will remain in cancel-only mode for at least 10 minutes before re-enabling trading. Sep 2, 03:59:27 GMT+0 - Identified - The DB maintenance is in final stages. We will perform internal checks after and enter post-only mode shortly after. Sep 2, 02:51:57 GMT+0 - Identified - The DB clean up is taking longer than initially estimated and trading will remain paused. We estimate another hour, but will update with a more concrete ETA as soon as we have it. Sep 2, 01:30:01 GMT+0 - Identified - Maintenance is now in progress Sep 2, 01:09:23 GMT+0 - Identified - Trading will be paused at 01:30 UTC, Wednesday, September 2 for approximately 1.5 hour. We are working with AWS to apply a final fix to their internal DB issue for the root cause of the database replica lag which includes several database tuning operations. There will be a 5 minute cancel-only mode that will be announced before trading is resumed, and any changes in ETA will be announced as soon as we have them.","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":"2026-09-02T01:30:00+00:00","first_seen_at":"2026-11-08T17:00:43+00:00","triaged_at":"2026-11-08T17:03:16+00:00","updated_at":"2026-11-08T17:03:16+00:00","category":"vendor","confidence":null,"triage":null,"analyst_status":null,"analyst_note":null,"search":"'+0':35C,47C,81C,110C,151C,164C '01':147C,149C,160C,171C '02':106C '03':77C '04':31C,43C '09':161C '1.5':179C '10':68C '2':30C,42C,76C,105C,146C,159C,176C '23':162C '27':21C,79C '3':18C '30':33C,148C,172C '35':44C '36':45C '5':215C '51':107C '57':32C,108C '59':78C 'affect':23C 'announc':224C,236C 'anoth':129C 'api':27C 'appli':187C 'approxim':178C 'aw':185C 'cancel':54C,62C,218C 'cancel-on':53C,61C,217C 'caus':199C 'chang':231C 'check':94C 'clean':114C 'clob':4A,28C 'cmtjeev5y0r221ao1t2g3qxau':9A 'complet':36C,39C 'compon':24C 'concret':137C 'current':51C 'databas':202C,208C 'db':84C,113C,194C 'durat':17C 'emerg':3A 'enabl':73C 'enter':97C 'estim':121C,128C 'eta':138C,233C 'final':88C,189C 'fix':190C 'gmt':34C,46C,80C,109C,150C,163C 'hour':19C,130C,180C 'identifi':48C,82C,111C,152C,165C 'inc':7A 'inc-polymarket-cmtjeev5y0r221ao1t2g3qxau':6A 'incid':11B 'includ':206C 'initi':120C 'intern':93C,193C 'issu':195C 'lag':204C 'least':67C 'longer':118C 'mainten':5A,16C,37C,85C,153C 'minut':22C,69C,216C 'mode':56C,64C,101C,220C 'op':12B 'oper':210C 'paus':126C,169C 'perform':92C 'polymarket':1A,8A,10A,13B 'post':99C 'post-on':98C 'predict':25C 'progress':157C 're':72C 're-en':71C 'remain':59C,125C 'replica':203C 'resum':228C 'root':198C 'schedul':2A 'sep':29C,41C,75C,104C,145C,158C 'septemb':175C 'sever':207C 'short':102C 'soon':140C,238C 'stage':89C 'success':40C 'take':117C 'trade':26C,74C,123C,166C,226C 'tune':209C 'type':15C 'updat':133C 'utc':173C 'vendor':14B 'wednesday':174C 'work':183C","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':4A 'cmtjeev5y0r221ao1t2g3qxau':9A 'emerg':3A 'inc':7A 'inc-polymarket-cmtjeev5y0r221ao1t2g3qxau':6A 'mainten':5A 'polymarket':1A,8A,10A 'schedul':2A","search_b":"'incid':11B 'op':12B 'polymarket':13B 'vendor':14B","search_c":"'+0':35C,47C,81C,110C,151C,164C '01':147C,149C,160C,171C '02':106C '03':77C '04':31C,43C '09':161C '1.5':179C '10':68C '2':30C,42C,76C,105C,146C,159C,176C '23':162C '27':21C,79C '3':18C '30':33C,148C,172C '35':44C '36':45C '5':215C '51':107C '57':32C,108C '59':78C 'affect':23C 'announc':224C,236C 'anoth':129C 'api':27C 'appli':187C 'approxim':178C 'aw':185C 'cancel':54C,62C,218C 'cancel-on':53C,61C,217C 'caus':199C 'chang':231C 'check':94C 'clean':114C 'clob':28C 'complet':36C,39C 'compon':24C 'concret':137C 'current':51C 'databas':202C,208C 'db':84C,113C,194C 'durat':17C 'enabl':73C 'enter':97C 'estim':121C,128C 'eta':138C,233C 'final':88C,189C 'fix':190C 'gmt':34C,46C,80C,109C,150C,163C 'hour':19C,130C,180C 'identifi':48C,82C,111C,152C,165C 'includ':206C 'initi':120C 'intern':93C,193C 'issu':195C 'lag':204C 'least':67C 'longer':118C 'mainten':16C,37C,85C,153C 'minut':22C,69C,216C 'mode':56C,64C,101C,220C 'oper':210C 'paus':126C,169C 'perform':92C 'post':99C 'post-on':98C 'predict':25C 'progress':157C 're':72C 're-en':71C 'remain':59C,125C 'replica':203C 'resum':228C 'root':198C 'sep':29C,41C,75C,104C,145C,158C 'septemb':175C 'sever':207C 'short':102C 'soon':140C,238C 'stage':89C 'success':40C 'take':117C 'trade':26C,74C,123C,166C,226C 'tune':209C 'type':15C 'updat':133C 'utc':173C 'wednesday':174C 'work':183C","cause_entry":null,"cause_path":null,"disclosures_checked_at":null,"first_public_at":"2026-09-02T01:30:00+00:00","kev":null,"cvss_vector":null,"cvss_by":null,"poc_count":0,"sources":[{"source":"statuspage","external_id":"polymarket:cmtjeev5y0r221ao1t2g3qxau","url":"https://status.polymarket.com/maintenance/cmtjeev5y0r221ao1t2g3qxau","severity":null,"published_at":"2026-09-02T01:30:00+00:00","modified_at":"2026-09-02T01:30:00+00:00","first_seen_at":"2026-11-08T17:00:43+00:00","fetched_at":"2026-11-09T01:51:41+00:00","note":null}],"documents":[],"disclosures":[],"exploit_sources":[],"notice":"Free to read, with fair use of about 60 pages a minute.
