I have to news one is Good and other one is bad

The good news every one know :p i mean it is that my oes tsetnoc still ranked at the top

But the bad news is that my hosting is performing very bad thats why my blog oes tsetnoc mostly down daily. Even when i was trying to write this post my website down more than 50 times (it take almost 30 mint to write this post just because of my *** hosting

This is very dangrous for me because google decreased thosed websites from their search results which are mostly down

What should i need to know? Buy another hosting?
