[@PowerPaul:] Damn... Perfect moment for that... I investigated right now. Looks like my domain/DNS provider has some struggle... I noticed a slow connection earlier today... I have to renew the domain this month anyway... Good time to move it to another provider.

Thank you very much for the info!

Update 1: no it is a hive related script from a third party it seems which causes the trouble - I should be able to replace it relatively fast.

Update 2: solved. https://unpkg.com had problems with their Content Delivery Network. i switched. Thank you once again! What a luck you saw. This started right after I published the article - because before I loaded the site without problems. Glad to have you, dear Servelle! Let me look for an unvoted article on your blog. ;-)
