I have been doing web developing for quite a long time now and it is very difficult for me if I am having this high down time rates. It is very simple, you have a website and it is supposed to be live all the time. How a reader can read if he or she is facing a blank computer screen? So picking one is very crucial, you have to know the history of it.
There are some types of web hosting service, sometimes they do not tell what is the type but most of the time they do. You might heard the dedicated server, from the word it self, it is “dedicated”. This is the type that the client leases the whole server without sharing with anyone. The good thing about this type is, you got all the disk space in your hand. The loading time is much faster because it serves only one, you are the only one that is using it.
The next one is the vps hosting or the virtual private server, most likely it is different from the dedicated one. What this vps do is, your physical server is partitioned into several server. Meaning, your are using some parts of the server from the other and some parts are coming also from the other. But in virtual perspective, you are having one server. Which is good actually, less chance that your website will go down. Why? Simply because each server acts a contingency sort of thing. If one goes down, the other will not. In layman’s term, it is some sort of a back up. Also, expansion will not be a problem to you if you are planning to. Because you are sharing some space form the other, you can simply acquire some space that is not occupied. It is a matter of choice actually. Reading is very helpful, try to read some guides about these.
