News Web Part rendering issues

I can confirm that in all of my tenants in Australia this now appears to have been resolved. I spent an hour on a support call with Microsoft who took logs via Fiddler, etc. but have yet to receive an explanation as to what caused the problem. Thanks to all who commnted and helped add eweight to the service request seriousness. I'll report back if I hear any more regarding what caused the issue and what the fix was.
