ICANN has recently approved the first rollover of the domain name system’s master security key. This means that, on October 11, 2018, they will delete the key-signing key that has been used as the trust anchor for the DNSSEC ecosystem since 2011 and will be replacing it with a new one.
How Does This Change Impact You?
Beginning October 11, you may experience service disruption if you have a domain with enabled DNSSEC. This may occur if your Internet Service Provider (ISP) has not updated the key on their side.
Service Disruption – What To Do?
First, try disabling DNSSEC for your domain. If this does not fix the issue, contact your ISP for further assistance.
