This weekend AAR will be upgrading our server network to accommodate systems for ARBI, which will soon enter final development and testing. Our internal and external systems will be unavailable on Saturday from 8:00am through 8:00pm and periodically on Sunday. Affected services will be and staff email as well as any network service. Unaffected will be AAR Transaction Management, eSign and zipForm®, as they are all accessed through their usual sites. We appreciate your patience as we make these upgrades!
