Anyone else having pages load or reload black [View all]

It’s been happening over the last several hours, not on the latest page but from clicking a thread on it … it starts to load the thread and goes black for several seconds, back to the thread text, then black again then the thread text again .
Sometimes it successfully loads but other times just goes black for good. Trying to reload it will pop up this:
Web server is returning an unknown error Error code 520

It’s pretty sporadic so not every thread doesn’t load
