Show HN: SadServers – Test your Linux troubleshooting skills

#1
Hello, I'm building SadServers.com, a SaaS where users can test their Linux troubleshooting skills on real Linux servers in a "Capture the Flag" fashion.

I hope this is useful, to learn more about the project please see https://github.com/fduran/sadservers

Seems like it's out of capacity:

    An error occurred (VcpuLimitExceeded) when calling the RunInstances operation: You have requested more vCPU capacity than your current vCPU limit of 64 allows for the instance bucket that the specified instance type belongs to. Please visit http://aws.amazon.com/contact-us/ec2-request to request an adjustment to this limit.
Maybe something like https://leaningtech.com/webvm-server-less-x86-virtual-machin... would be cheaper and more reliable for this kind of thing?

Yes, HN effect lol-sob.

Mitigation: reducing servers life time temporarily so more people can try.

Yup, that's what I was afraid of.

Usually I roll my eyes when someone posts their own website to HN and it crashes under load. But given the nature and complexity of yours I think there's room for understanding and patience :)

That doesn't mean that I'd charge individual users :-)

Heck, I'm not even asking for an email (and I had to do extra session management coding for that).

Thanks, I did some stress-testing and infra is scalable enough but I forgot about the AWS quotas, my bad. Quota increase requested and servers are killed off so hopefully "soon" the issue will go away.
