Even though currently your domain is only using DNS only mode, so there is no chance of slowness. As domain directly points to the Bluehost IP. Still, the server response goes above 1 minute which indicates you do have problem at Hosting end. It could be due to site being under DDoS attack or something else. In general, a shared hosting like Bluehost usually can be slow.
For hosting it’s all ok. I should find what create scripts, because they can’t kill processes. Processes back again. I’ve done some changes on Cloudflare 1-2 months ago. Maybe they create troubles? Can you help?
