Hello,
Thank you for bringing this up.
I can confirm this is part of a wider internet outage and isn't Meraki specific.
You can see additional information on the outage here and here
Due to the nature of the outage, we are seeing a significantly higher number of calls which is leading to increased wait times. Thank you for your patience.
(Just to confirm, I do work for Meraki but it will take a few days for my account to be verified.)
