Scalable and no loud neighbor in the upcloud – your experience for cloud host without any problems?

Hello,

I use upcloud for about 2 weeks – very nice cpanel and support – but I have problems with noisy neighbors. I've been with servint for over 10 years, but had to cut costs because of a large hosting client for cost reasons. So I have the 6cpu 16gb RAM and works great, but suddenly very large CPU load and it is from another neighbor, not from my clients, since the TOP command shows normal usage for my server but huge CPU usage (15 – 40) suddenly).

Anyway, what was your experience, a recommendation for a scalable host like Upcloud, but no loud problem with the neighbors or is it just not possible? I use Cpanel / Cloudlinux, a great combination and I want to continue with it.
