Well then.. This is a bit awkward…
We’ve moved our website to a new webhost, but forgot to update the DNS settings of our domain name. So MysteryLAN.nl still pointed to the old webhost and all changes were made on this old webhost, which was cancelled last week. As a result: No more MysteryLAN.nl!
We restored a backup we had, but this is missing some of the content changes of the last couple weeks. It will take some time to update everything again. But not to worry, it will be done :)
Long story short: We’re idiots, but everything is working again.
