The server maintenance on the frontend side is completed. We moved to the new server and we were able to optimize the page even further. Everything should load immediately now, even if there are many connections in parallel. If you have any trouble accessing the site, or if the page is very slow for you (but other websites load fast), please contact us.
We need to do some more work on the backend side, but this shouldn't affect availability of the website.
Furthermore we are working on a bigger update for the website, so expect new things in the upcoming weeks :) If you have any feature request, don't hesitate to share them with us, either via e-mail or via GitHub through the link at the top.
Thank you for your patience throughout the last weeks, were the availability of the website was not always 100%.
