Hello, The infrastructure behind this mailing list has been upgraded. IANA hosts a number of operational mailing lists using ICANN's mailing list infrastructure. This infrastructure is currently undergoing a major upgrade, including to the mailman software that operates this list. Users should not observe a difference except for modernization of the mailing list administration website. Mailing list archives has moved to a new archiver, but old archives will be retained to preserve references to archived messages. If you have problems caused by the migration, please contact the IANA team at iana@iana.org so we may help remedy them. Please find the new administration interface, including the new archives, at https://lists.iana.org/postorius/lists/register-urn.iana.org/. Best regards, David Dong IANA Services Sr. Specialist
