Is the server down. I can't get online with Core.
How are you posting here? Have you tried with another router? Maybe it is just your ISP having issues.
DB2 - Please power cycle your Core and recheck your app to make sure its talking to the Core router. I haven't seen any outages that would cause Core services to stop working. If you are not able to get online at all reboot both your ISP device and Core at the same time and recheck connectivity.
