Is HeRO stable?

[SilverBeast]

Hi,

I come from a server that is always messing up, and is always crashing, and honestly I am kind of tired of it. Is HeRO really that stable? Will I be ensured that on weekends (when almost everyone signs on) that the server will be up and running? Like anyone else I understand unexpected crashes, and maintenance but will there ever be times that the server locks up for more than 2 days, has that ever happened, and do you think this server has the potential? Thanks in advance!
