EDIT: Maintenance is now completed.
We are scheduling a maintenance window on January 20th starting at 11am ET. We are hoping to limit the downtime to under 2 hours.
I believe this is our first scheduled maintenance since the launch of Adafruit IO.
If you are connecting via mqtt, we are anticipating that your data will still arrive, but will not process until the maintenance is completed (this is dependent on the length of the downtime, and is not guaranteed in any way). New connnections to mqtt during this window may be rejected until the maintenance is completed. The API and web front-end will be taken down entirely during this time.
