We've managed thousands of different servers for our clients over the years. Some customers ask why we do not offer Windows VPS Servers, and this is simply because we prefer to avoid Windows.
Windows servers in general are less reliable and more prone to hacking and other failures, compared to the average Linux server. We do realize Windows can be reliable and secure, but it is no match for a default Linux VPS configured with a distributiion such as Centos or Debian.
Even if you are not familiar with a Linux VPS (Virtual Private Server) we strongly recommend investing in one and keeping as much of your web and company's infrastructure inside one.
They are the most reliable and deliver the best value, even when money is not a factor.
