Do you have the site crashing occasionally, also? Sometimes it goes down multiple times in a day for me.
Yes, and that's from the host called Cloudflare.
It's common, unless the site owner pays for a dedicated server for high availability.
This site is on a server with many other sites, that's how the host makes money.
The price is cheap in this config, but the price can get very high on a dedicated server because then they won't allow many other pages on the same server. It's only you and maybe a dozen other people, that's why it's called "High Availability".
