Is it possible ?
These people are the “Unlimited Bandwidth and Unlimited Disk Space” companies. If you have not heard it elsewhere, please allow me to be the first. There is no such thing as unlimited bandwidth. Typically the way it works is that a large corporation will rent out small chunks of the bandwidth they are capable of providing to smaller companies. These smaller companies turn around and do the same to the web hosts. These web hosts, again, do the same separation method and sell these small “chunks” to you based on your needs.
These unlimited web hosting companies are banking on the idea that you will never use more than what you might would have used if you were using a package from a web host that does not offer these types of promises. There are several problems that can be caused when running into these types of promises.
If the web hosting company that offers the myth of “unlimited bandwidth” does monitor well, they will shut your website down if you do exceed what their own limitations are for your website. They will not risk having their server shutdown or losing their other customers simply because you are using too much bandwidth. Therefore, no one actually provides real unlimited bandwidth. It simply is not possible.
A severely unmonitored web hosting company can end up having a customer use up all the space that they were allotted by their datacenter. In this case, every person using the server (all clients under the web host) will have their websites go down because the datacenter will either shut off the server when the web host exceeds their limit. If that does not occur then they will charge the web host with huge bandwidth fees. The end result will quickly lead to the web hosting company being upside down in their profits and they will likely be forced to close the company. The end result being the same, your website being offline.
