I broadly agree with what you're saying, but, that's not the issue here.

They don't even have a dedicated status/outage page, afaik.

The website being down is a more classic problem. The outage probably increased traffic to their website by 1000x if not more and the infrastructure for the website simply couldn't cope.

Good lesson on keeping your status infrastructure simple and on something which is highly scalable.

Having a CDN where the main page of their site was 99% cached globally would have probably mitigated this issue.
