While it's not a customer friendly viewpoint, it's not exactly what happened here. You have to consider what is being provided and how much was paid into it for said service. Had they been paying a lot of money for solid DNS I could agree with you, but they weren't.

It's a completely free service. With an extremely low price for domains.

Even though it's become almost a standard for domain registrars to provide DNS, it's still free. I've been using NC for years for my business (also a free service) and the downtime for what it provides has been mostly minimal.

Now if I was paying namecheap specifically for enterprise DNS something like $10/month or $40/year and it included DDoS protection then yes I should be compensated. Namecheap gave people what they paid for - a domain, the DNS is just a really great perk.

If namecheap chose to stop assigning all customers the same list of DNS servers, it would benefit namecheap as well. There's 200+ people in the queue for live chat right now :)

It's not DDOS mitigation or H/A, or some other high end feature.

The only way this would be successful is if the "customer IP's" were spread accross separate networks, and the announcement for the attacked network was sent somewhere else.

Assigning customers across lots of IP's in the same /24 isn't going to do anything. A volumetric attack is still going to succeed there.

In this landscape of ever-dwindling portable IPv4 subnets, it's harder and harder to get a /24. You won't get an assignment if your justification is "to fight a DDoS."

So namecheap would need a few different, separate IPv4 subnets.

Like the ones they already have?

Good point. They should be spreading things around more.

That's what insurance is for.
