This is not a sharp picture - not even that good. I was flying early in the morning friday July 19th when I realized something was really wrong. The ticket counter was in a flurry of checking lists and creating paper tickets. I would learn within 30m that Spirit Airlines was SOL in the airport and the TSA was checking my paper ticket against printed manifests. I couldn't be prouder of my own teams at work for having dug in and weathered the Crowdstrike storm - it's a testament of having skilled, available and committed SREs. By the time I landed and was back at my desk to help, the main production systems were healthy. I can't really speak to the rest - but my day wrapped later than usual friday but it was an amazing team effort and really, I couldn't be prouder of the people I work with at WellSky
