[attila]

Hello

When advertised 99%, 99.9% or 99.999% uptime guaranty is it per month or per year ?

Thank you

That depends entirely on the company making those statements. Usually though it's taken to mean monthly, although if in doubt - ask them

It should have been done monthly. That's the norm in the industry.
