Thank you to everyone for bringing this to our attention. Our instances of e-root are supported by both CloudFlare and PCH. While troubleshooting this issue this morning, PCH sent an email to let us know that they became aware of the error and have now resolved the issue. The error was causing intermittent issues of SERVFAIL replies. PCH has made updates to ensure this does not happen in the future.

In regards to the contact form, we are looking into why an email was not forwarded to the NASA team.
