I moved from my previous hosted to DO (not migrated yet) because, I thought, I had a lot of downtime and my servers were often out of reach. I recall, I thought so. Yesterday, I found out that my servers haven't been down at all, but because of security (too many requests via ftp / Too many open connections (TCP/SMTP/FTP) my IP was blocked for a few minutes. It feels like downtime, but instead it's just a matter of protection.
While security is great, being blocked for a few minutes, up to 15 in my experience, is terribly annoying. The rather worse thing of it, is that this problem occurs about at least a few times a week. However, once again: security is great. Because of that, I'm unsure what to choose. Ease of use or just be happy there is/was at least that kind of protection.
To come to the questioning part, I've got two questions:
1. What is your personal opinion about this? Would you favor this kind of security or would you be annoyed yourself because of it?
2. How would you deal with security on your own server?
// It if matters: Mainly regarding Ubuntu servers, as I'm currently only using Ubuntu's.
