OT: Changing VPS provider

After seven years with ServInt, I am researching other VPS providers. Over the past four days, My server has been down about 15 times, for periods of a few minutes to over an hour. My clients have been furious with me, and I have in turn unleashed that fury at ServInt. A serious problem like this should never persist for four days.

Although ServInt has promised me that the problem is resolved, this disaster has eroded client trust in me and caused huge headaches for the clients, who use my web application in their daily business transactions.

I am strongly considering Amazon Web Services as an alternative. They have a bewildering collection of services, and their pricing is difficult to grasp, but they have an "introductory" product called Lightsail that provides basic packages at less than half what ServInt charges. It also seamlessly ties in with the Amazon CloudFront CDN, which is attractive to me because I have clients in Asia and Europe.

(Lightsail package example: 8GB memory, 2 core processor, 80GB SSD, 5TB transfer for $80/mo.)

I don't want to spend a lot of time test driving Amazon or any other provider until I narrow down the choices to two or three. If anyone has an alternative to Amazon to suggest, or any experience with AWS to share, I'd like to hear about it.
