I had this issue between 8:50am and 10:50am Eastern. I reported it to NetSuite and they are still asking me questions like "what is your domain name" 🙄 It did seem to resolve itself for me around 10:50am, though. It may be related to today being the deadline on the new Scriptlet URL parameter requirements. If you received an email about that, make sure your Scriptlets have been updated with the new &ns-at=XXXXXXXXXXX parameter when they are called.
