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 .NET zone
will be increased in size from 1024 to 1280 bits.
On July 10, 2019 the 1280 bit ZSK will be pre-published in the .NET
zone. On July 15, the .NET zone will be signed with the 1280 bit
ZSK. On July 20, the 1024 bit ZSK will be removed 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.
