Since HTTP/2 became supported for Shared Hosting, I’ve been seeing the .well-known folder in my accounts base directory via FileZilla SFTP.
It was never in that location before. Prior to HTTP/2 on Shared Hosting, this directory was tucked away beyond reach (CHMOD setting.)
As the name would imply, this directory is used to store several files often requested by various User Agents, mostly bots but also browsers.
Here at DH, this is also where the security certificates are (were?) kept and updated.
• Why was it moved to our account base directory?
• Is it safe to upload these various files (example: dnt-policy.txt) to this directory?
• When I open the directory, I see only another directory named: acme-challenge. When I open that, it is empty. What’s this?
