For the first time, my website reached 1,000 clicks in 28 days in Google Search! For me, a reward for my work, as well as a stimulation

It's done (at least partially)! My website is installed on a VPS and thus will stay online during the transition phase,
where HelioHost rebuilds their servers. It was a rather hard work for a non-professional, but being hosted by HelioHost has one very big advantage: the
power of their community forum. Thanks to all those, who helped me with some advice during the last days! For the site visitors, nothing has changed. The
same address (www.streetinfo.lu) and as on Tommy a secure connection with https.

Up from today, all data transfer to and from my site will be encrypted (usage of the HTTPS protocol by default). In fact, all access
via the insecure HTTP protocol is redirected to HTTPS. This ensures, that everybody, that visits the site, will have a secure connection. Thus, new URL:
https://www.streetinfo.lu. One drawback, however: The HelioHost servers use TLS 1.2 and, having a shared IP address, my webserver uses autoSSL, depending on
Server Name Indication (SNI). This means that older operating systems and older webbrowsers (e.g. Internet Explorer 6, standard browser
on Windows XP; not sure if Windows XP is able to connect with Firefox) will no longer be able to access the site.
