Should a hoster prevent ddos ​​attacks?

Question

DDoS Protection

Please tell me, for example, there is a hoster that has tariffs for vps, if a ddos ​​attack occurs, the more expensive the tariff, the better the vps can withstand the attack? Or does it depend on what the backend is written on which is hosted on the vps?

Answer 1

if a ddos ​​attack occurs, the more expensive the tariff, the better the vps can withstand the attack

In theory, yes. Strong iron will last longer.

Should a hoster prevent ddos ​​attacks?

Unless it is written in the tariff or contract. In 99% of cases, you will simply be dropped from the service if their host is trumpeted because of you.
And yes, it is almost impossible to protect yourself from dudos. "Practically" - because the services that can help with this charge so much that the amount paid for this is much higher than the potential losses due to dudos.
