{"id":"INC-circleci-rfz5wdpg2nl0","kind":"incident","aliases":[],"related":[],"title":"CircleCI: Delays starting jobs on Docker (Gen 2) resource classes","description":"On July 13 between 15:30 UTC and 22:40 UTC, we experienced delays starting jobs on Docker (Gen 2) resource classes due to capacity constraints from our cloud provider. The same issue recurred on July 14 between 15:45 UTC and 22:50 UTC.\n\nDelays reached up to 25 minutes on July 13 and up to 24 minutes on July 14. The medium+ and 2 X-large+ resource classes saw the longest waits. Earlier updates in this incident reported figures based on average wait times, which didn't reflect the maximum impact some customers may have experienced.\n\nWait times have now returned to normal. We are continuing to work with our cloud provider to add capacity ahead of the next peak period. Thank you for your patience.","summary":null,"severity":"medium","cvss":null,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"CircleCI","fixed":[],"affected":"","ecosystem":"vendor"}],"ecosystems":["vendor"],"tags":["ci","circleci","incident","ops","vendor"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"resolved","published_at":"2026-07-14T22:54:42+00:00","first_seen_at":"2026-10-23T19:12:22+00:00","triaged_at":"2026-10-23T21:57:05+00:00","updated_at":"2026-10-23T21:57:05+00:00","category":"vendor","confidence":null,"triage":null,"analyst_status":null,"analyst_note":null,"search":"'13':23C,74C '14':57C,82C '15':25C,59C '2':8A,40C,86C '22':29C,63C '24':78C '25':70C '30':26C '40':30C '45':60C '50':64C 'add':137C 'ahead':139C 'averag':105C 'base':103C 'capac':45C,138C 'ci':16B 'circleci':1A,13A,15A,17B 'class':10A,42C,91C 'cloud':49C,134C 'constraint':46C 'continu':129C 'custom':116C 'delay':2A,34C,66C 'didn':109C 'docker':6A,38C 'due':43C 'earlier':96C 'experienc':33C,119C 'figur':102C 'gen':7A,39C 'impact':114C 'inc':12A 'inc-circleci-rfz5wdpg2nl0':11A 'incid':18B,100C 'issu':53C 'job':4A,36C 'juli':22C,56C,73C,81C 'larg':89C 'longest':94C 'maximum':113C 'may':117C 'medium':84C 'minut':71C,79C 'next':142C 'normal':126C 'op':19B 'patienc':149C 'peak':143C 'period':144C 'provid':50C,135C 'reach':67C 'recur':54C 'reflect':111C 'report':101C 'resourc':9A,41C,90C 'return':124C 'rfz5wdpg2nl0':14A 'saw':92C 'start':3A,35C 'thank':145C 'time':107C,121C 'updat':97C 'utc':27C,31C,61C,65C 'vendor':20B 'wait':95C,106C,120C 'work':131C 'x':88C 'x-larg':87C","nicknames":[],"mitigations":[],"who_affected":null,"tier":null,"verified":{},"analyst_revisit_at":null,"first_public_at":"2026-07-14T22:54:42+00:00","kev":null,"cvss_vector":null,"cvss_by":null,"poc_count":0,"sources":[{"source":"statuspage","external_id":"circleci:rfz5wdpg2nl0","url":"https://stspg.io/0t40l14n15yl","severity":"medium","published_at":"2026-07-14T22:54:42+00:00","modified_at":"2026-07-15T00:32:55+00:00","first_seen_at":"2026-10-23T19:12:22+00:00","fetched_at":"2026-10-25T23:24:49+00:00","note":null}],"documents":[],"notice":"Free to read at a human pace.
