Thank you for letting us know about this issue. We will take a look shortly. Thanks.
Same here -- https://appsforoffice.microsoft.com/lib/1/hosted/office.js is not loading from Canada (but is apparently fine from Portugal, according to other team members)
Problem is affecting other Office apps as well.
I tested with a service that loads the page from multiple locations. Results can be seen here: https://semonto.com/tools/website-reachability-check?test=a60f4a2e6c573f1
We are also having reports of our Outlook ItemSend Add-in hanging when trying to reach office.js
MSFT has reported service issues with M365, likely related?

The issue seems to have been resolved by now.

Same here with our Outlook add-in, multiple reports from our customers.
Issue was resolved but is now occurring again.
Looks like the issue has resolved itself again.
@shanshanzheng-dev What steps can we take to mitigate this issue should the CDN go down again? Is it safe for us to self host the office.js file as a backup?
Thanks for reporting this issue. Yes, looks like the issue has resolved again. We've connected with our partner team to consider on future for a fallback mechanism and we'll also keep monitoring if it occur again. Thanks.
@shanshanzheng-dev We'd like to follow up on the fallback mechanism effort. Is this something your and the partner team will handle internally so it is transparent to us, or do we need to manually configure the fallback when loading the evergreen OfficeJS script?
Thanks @bchen-hs-eng. Hi @gergzk We think it makes sense if customer manually configure the fallback when loading the evergreen OfficeJS script. Not sure if you have some good insights about the fallback mechanism, seem office.js deployment/CDN is out of our control.
Per https://semonto.com/tools/website-reachability-check?test=2d7e174246175b34292aff94725551bc6a80 this is fine now, so I'll close with comments.
Developers should not bundle office.js with their add-in.
If in the future this is observed again, a network trace of attempting to get the office.js file would be most useful, as well as a session id (eg: File -> Info, copy/paste session id)
