My favorite hosting platform is the CSIS Server. That is because it is reliable and I can always log into it. It is also pretty fast. M-drive is extremely slow and sometimes won't let me log in. 000webhost is also unreliable as it is sometimes offline. In fact, it is offline at the moment I am writing this paragraph. Therefore, because the CSIS Server is fast and reliable, it is my preferred hosting platform.
I chose to host on the CSIS server because it is the one I am most familiar with. It is also pretty reliable.
