DNS Migration Tuesday, 23 April, 10:00 EDT

The OSG will be performing a migration of the nameserver for and next Tuesday, 23 April 2018, starting at 10AM EST.  Given the level of caching within the DNS infrastructure, it may take up to 24 hours for the change to fully propagate.

The migration is expected to be completely transparent to all sites and not require any action.

However, there remains some risk of interruption, particularly around the delivery of email messages to lists.  If you see any issues next Tuesday, kindly reach out to or, for non-email-related issues,

If you have any questions or concerns, feel free to reach out prior to the transition.
