Missing Piece Graphics

Martin_Stahl

The site is currently experiencing an issue with a third-party content delivery network (CDN) causing some members to experience missing graphics in Live/Daily chess and tactical boards.

Staff is currently working to resolve the problem.

I saw a message blaming it on Amazon. 

Why would problems at Amazon affect chess piece display?

their cloud probably

The site uses a content delivery network (CDN) for a lot of static graphics. My guess is that the CDN is hosted on AWS.

Yeah, I was wondering what Amazon has to do with it too.

The key word is "static graphic" -- why not to cache it on the local machine???

Pretty sure they are and that is why a cache refresh is often suggested when graphics have issues. But there is often an time they still get refreshed and if the CDN servers have updates, the browser will reload those. I don't know the specific issue, that is causing it in this case.

So, I did the following: opened Settings, changed Pieces from Wood (no white rooks and black pawns) to something else - works as a charm immediately, while Settings GUI remains open; changed back to "Wood" - white rooks and black pawns disappear, literally. I would say, that makes me think no "Wooden" white rooks and black pawns were in cache at all.
I am not a guru in HTML, but haven't seen "cache" keyword in the page source.

Caching is a browser feature, to prevent the need to download resources every time a page loads.

There are methods in HTML/JS/etc. to control how a browser caches (or does not cache) some elements, including validity time. There is nothing about it in the source code (as far as I can see), that's what I mean. On the other hand, I do not see why caching the pieces graphics may hurt Chess.com's functionality. What we all see now, the otherwise breaks it.

I have had this issue happen a few times in the recent past, but everything looks fine now. Weird. Thanks for the info on Amazon, I was also wondering what they had to do with anything on here.

The third-party content delivery network the site uses apparently is hosted on Amazon Web Services.
