I suppose you need to get more reliable options. I can say Hostzealot.com is offering top server deals. They are experienced host with high performance, stable network and available team. Prices are reasonable

if you are interested in getting a quality VPS account, use it from time-tested companies, I mean hostingsource.com and hostsailor.com.
They have stable servers whcih cost not much and there is no downtime on them.
They have an amazing support which is active around the clock.

To my mind the perfect server hosting solutions are offered by WooServers.com. They are experienced host with responsive support, low-cost plans and solid server hardware, no matter what location of server is needed.
