Yes, we've been testing volume attachments every 5m since start of the year, and have experienced 100-150 attachment failures per volume type in that time frame during multiple events (most recently last week): https://cloudlooking.glass/dashboard/#aws.ebs.us-east-1--cp--attach-volume-*&c2&1y https://cloudlooking.glass/dashboard/#aws.ebs.us-east-1--cp-... Another interesting bit, is last March AWS changed something in the control plane which both triggered a multi-day LSE, and ultimately increased attachment times from 2-3s to 10-20s (also visible in the graphs).
