Expected or Desired Behavior

A SharePoint WebPart should always load from the O365 CDN when using Assets Packaging.

Observed Behavior

It works and then... it stops, without changing anything. We are seeing more and more (and customers are reporting more and more) of issues that WebParts files can't be found in https://publiccdn.sharepointonline.com/*.

We're getting those errors in the UI:

And when we can reload to get the network trace, we get something like this (both screenshots are not related, it happened in 2 different sessions):

Steps to Reproduce

This one is really hard to reproduce and we had a good discussion at Ignite with @patmill about this specific issue. Sometimes it fails, then a reload and it starts working again... Basically, deploying a webpart using Assets Packaging and wait for sometimes and be lucky (or unlucky!).

Thank you for reporting this issue. We will be triaging your incoming issue as soon as possible.

We are having exactly the same problem. May be related to this issue here #1731 as the behavior is the same.

Any update on that issue? We got reports today from a couple of customers today... Thanks!

[sebastienlevert]

Update from today. We're experimenting the following:

But still, the actual file being referenced is available and works. Reloading the page does not make anything disappear and we still see the error.

Emptying the cache makes it work, though... Any update on this issue? Are we doing something wrong? @patmill @VesaJuvonen
