AASHTO re:source Website Maintenance April 11-14, 2025

Apr 07, 2025

The AASHTOresource.org website will be taken offline Friday, April 11 at 5:00 p.m. EDT. We will be migrating our systems to a new data center over the weekend.

We expect to restore service on Monday, April 14 at around 10:00 a.m. EDT. If this timeframe is extended, updated information will be provided on a temporary page at AASHTOresource.org.

During this outage neither customers, nor staff will have access to the site, including laboratory contact information, assessment report details, corrective action responses, accreditation listings, and any other data.

We apologize for the inconvenience.

If you have any questions about this outage, please contact info@aashtoresource.org or call 240-436-4900.
