We have no idea what their contract is. But two business days without a reply isn’t exactly a long time. Especially if they are conducting their own investigation and reproduction steps.
My impression from reading the writeup is that CF did receive support and communication from Flexential during the event (although not as much communication as they would have liked), but hasn't received confirmation from Flexential about certain root cause analysis things that would be included in a post-mortem.
Two days without support communications would be a long time, but my original comment about the two day period is about the post-mortem. It's totally reasonable IMO for a company to take longer than two days to gather enough information to correctly communicate a post-mortem for an issue like this, and IMO its unreasonable for CF to try to shame Flexential for that.
What???? We have 4 hour boots on the ground support with Supermicro and that's a few thousand dollars a year lol.
That doesn't make any sense for a customer as big as CF.
