Hosting is invisible until it fails, and then it is the only thing anyone cares about. We learned this keeping news portals online through traffic spikes, and we apply the same approach to business sites: right-sized resources, caching in front of the origin, a CDN for static assets, automated backups, and monitoring that tells us before it tells your customers.
We are equally happy to advise rather than host. If your setup is working, we will say so. If you are on a shared plan that throttles every time you get featured somewhere, we will show you the numbers and let you decide.
