Phasing out hosting server after (almost) 10 years

After having been running steadily on the previous server for almost ten(!) years, it became time to retire that machine. So, ManyTools has now been moved to a shiny new hosting cluster. You may/should notice some speed improvements. In case you notice any problems or irregularities I'd be happy if you notify me so I can check on them.

Exit Coinhive (in-browser bitcoin mining)

Thank you for your feedback on our (brief) test with browser based bitcoin mining. This seemed like a nice way to support this website, but turned out to be far too much of a burden to our visitors. So we've decided to remove it. Our apologies for the inconvenience it has caused.

Migrated to HTTPS

Happy to inform that Manytools is now fully Chrome-62-ready, thanks Google! A secure connection had been due for a very long time. Today we finally got around to upgrading the site to run on HTTPS. – (Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode.)
