For those of you using the off-site backup services from Carbonite, I received this notice:
We just wanted to let you know that we will be performing upgrades and maintenance on the servers your data is stored on over the course of the next week. During this time, we anticipate you may experience a brief interruption in access to the service. We aim to complete this maintenance as quickly as possible, and we will send an update to you as soon as the service is fully accessible again.
