Gateway time-out on compendium entries

Trying to access several compendium entries and I get 504 errors consistently across browsers and devices. - Warlock - Warlock: Creating a Warlock - Tanarukks about 40% of the things I try to access in the compendium fail this way.

Hello Cary B., I'm sorry to hear that you're having issues with the site. To rule out potential issues, please carefully work through these steps of our guide to  Solving Technical Issues : Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome  and  Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable  all  add-ons/extensions. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through all of  Step 4 .  (Don't forget the complete Console Log!) Thank you!

It's all working today with no changes from me.  I guess there was a server issue in Seattle that was fixed.  Maybe too much interest in the reduced price on the WOTC compendiums?
