I read the documentation about verifying domains in Amazon SES, and I don't understand - how long does the domain verification last and does it expire?

What happens if I remove the DNS settings after I verified a domain? I tried to do it with the DKIM DNS settings, and there I received a notification that the DKIM of the domain would be revoked, unless I restored them. But with the domain itself, I removed the DNS settings and I didn't receive any notification.

I'm running Nginx and uWSGI on my Ubuntu 18.04.6 LTS server. I checked the version of Nginx and it's 1.14.0. The uWSGI version I'm not sure, how do I check it? And is there a reason to upgrade Nginx and uWSGI for security reasons? Is there a known security vulnerability in any of them?

If I do need to upgrade, what is the best way to upgrade them? Can I do it with sudo apt update and sudo apt upgrade? I ran both of them but it's still Nginx 1.14.0.

I'm configuring a new server (droplet) with Ubuntu 18.04.1 LTS. I installed apache and configured virtual hosts. The server name is www.speedysoftware.com and this is the value of /etc/hostname. The problem is, I'm trying to redirect http://www.speedysoftware.com/ to a specific virtual host, but it's redirected to the default virtual host. On the other hand, http://www.speedysoft.com/ and http://www.speedy-software.com/ are redirected to the correct virtual host, which should be the same as http://www.speedysoftware.com/

File /etc/apache2/sites-available/000-default.conf:

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.

You can see that http://www.speedy-soft.com/ is redirected to the default virtual host, and this is correct. What is the problem with the configuration?

After I made changes, I reloaded the settings by sudo systemctl restart apache2.

Regarding redirecting, in this case I don't want to redirect. I want them to be considered separate websites although they lead to the same virtual host. In other cases I do redirect, for example I redirect http://www.speedypedia.org/ to http://www.speedypedia.info/, and I redirect http://ww.speedysoftware.com/ (or any other subdomain, including http://speedysoftware.com/) to http://www.speedysoftware.com/.

Update - I checked and http://ww.speedysoftware.com/, http://wwww.speedysoftware.com/ and http://speedysoftware.com/ all lead to the correct virtual host. Only http://www.speedysoftware.com/ doesn't lead to the correct virtual host.

I'm trying to setup an Ookla server for speed test. My OS is Ubuntu (20.04 LTS) and I installed the script, also set it up to start after reboot, but I don't know how to set it up to work with HTTPS. The test page says my server passed on netgauge, websocket and crossdomain but failed on https. I would also like to know how I use my server for speed testing before I upload it to Ookla? I would like to know what is the speed and how it performs. I didn't find much documentation on Ookla's website, for example I didn't find how to setup HTTPS. If I get a certificate from Let's encrypt, how do I install and use my certificate?

For installing the server, I followed the links on https://www.speedtest.net/speedtest-servers.
