issues with accessing the AUR?

its since some hours or so that I get very often timeouts and/or "500 Internal Server Error" while accessing the AUR. It is fine for some seconds, sometimes minutes and then fails again. An example call done by the AUR helper (yay) is: https://aur.archlinux.org/rpc?arg%5B%5D=abootimg-git&arg%5B%5D=bcm4350-firmw... error on the CLI is: "net/http: TLS handshake timeout" error at the web is: "500 Internal Server Error" this is not that specific query though. it happens also just with opening https://aur.archlinux.org in a browser.. hope this is nothing serious :/ tested that on different systems.. Cheers Thomas
