Yes, I did.
They told me there is another VPS abusing the network, but I don't think it's a good reason for 5 hours down time.
I agree, they should have a live monitoring system that should notify them when a server crashes.
They actually own data centers so there is no reason this happened for 5 hours, considering if it was monitored live, they would have known the server was down and would only led to minutes of downtime an hour at most.
As another thread of official burstnet account said: this is unmanaged service, this is what you got by the paid.
Okay an unmanged VPS going down is usually going to be the VPS owners problem,
But if the host node (Server that host all the vps) goes down, that is the Host Problem. They should have live monitoring software installed on those nodes, but to tell you the trust, I've noticed alot of Providers lately that have to be told about a problem with the host node.
