    Scheduled - To improve DNS resolver performance, we’re rolling out a change to our resolvers in each data center. This change will be deployed gradually to all data centers between January 16th and January 26th, and will help better balance the distribution of queries across our resolvers. We’ll roll out these changes at 08:00:00 EDT (12:00:00 UTC) to each data center on the dates specified below:

    Atlanta Monday, January 16th
    Dallas Tuesday, January 17th
    Newark Wednesday, January 18th
    Fremont Thursday, January 19th
    London Friday, January 20th
    Frankfurt Monday, January 23rd
    Singapore Tuesday, January 24th
    Tokyo 1 Wednesday, January 25th
    Tokyo 2 Thursday, January 26th

    Within 12 hours of this change being deployed, Linodes in each datacenter will renew their DHCP lease and pick up the new resolver addresses. Any firewall rules you have in place may need to be updated to accommodate the new resolver addresses.

    A full list of the resolver addresses is available in the “Remote Access” tab of your Linode’s Dashboard in the section labeled “DNS Resolvers”. Since this change will be applied to all data centers, you’ll want to review the resolvers list for each data center, and update your firewall rules accordingly.
