Verisign is in the process of increasing the size and strength of
the DNSSEC Zone Signing Keys (ZSKs) for the top-level domains that
it operates. As part of this process, the ZSK for the .COM zone will
be increased in size from 1024 to 1280 bits.
On October 10, 2019 the 1280 bit ZSK was pre-published in the .COM zone.
On October 15, we plan to sign the .COM zone with the 1280 bit ZSK.
On October 20, we plan to remove the old 1024 bit ZSK from the zone.
We do not anticipate any problems from this upgrade. In accordance
with our normal operating procedures we have a rollback process should
it become necessary to revert to the 1024 bit ZSK.
