The AcceptIO servers have been continuously running for over 2 years. It's finally time for some downtime, and it will be happening on 29 June (with a fallback date of 30 June) at 11am Pacific time, 2pm Eastern time. We are scheduling the downtime for 1 hour, but we expect it to take less than 15 minutes.
The purpose of this maintenance is to perform operating system and equipment upgrades. If all goes as planned, you probably will not notice any significant difference between before and after. The maintenance will include IP address changes on the server side. That should be transparent to you, but if you have trouble connecting you may have to close and restart email applications.
