Frequently Asked Questions (FAQ)

How do 99.9% and 99.99% uptime differ in practice?
99.9% uptime = a maximum of 8 hours 45 minutes of downtime per year. 99.99% = only 52 minutes per year. 99.999% (Five Nines) = only 5.25 minutes per year. For a typical website, 99.9% is sufficient. E-commerce that takes orders around the clock needs 99.99% or higher to be suitable.
How do Shared Hosting and a VPS differ in simple terms?
Shared Hosting is like renting a room in an apartment building, sharing the lobby, elevator, and infrastructure with others. It's cheaper, but if a neighbor uses a lot of power, it can affect you. A VPS is like your own condo, with clearly separated resources that don't affect each other, but more expensive.
How do bandwidth and speed differ?
Bandwidth is how big the "pipe" is; the bigger it is, the more data can be sent. Speed is how fast the water moves in the pipe. A slow-loading site may be due to a slow server (insufficient CPU/RAM), not insufficient bandwidth. For most websites, bandwidth is sufficient.
What does a CDN help with?
A CDN (Content Delivery Network) is a network of servers distributed worldwide. When a visitor requests a file, the CDN serves it from the nearest server, greatly reducing latency. For example, a visitor in Europe accessing a site hosted on a Thai server will, with a CDN, pull from a European server instead.
