As of today, I am unable to access the Extension Manager in few different NetSuite accounts. I keep getting this error for all of them :

{
  "header": {
    "status": {
      "code": "ERROR"
    },
    "message": "The host you requested <https://xxxxxxxx.app.netsuite.com/app/site/hosting/scriptlet.nl?script=1483&deploy=2&compid=xxxxxxx&service_name=FILE_SERVICE> is unknown or cannot be found.",
    "extra_data": {},
    "error_code": "SSS_UNKNOWN_HOST"
  }
}

Anyone else seeing this or have any ideas?
