  We conduct longitudinal and temporal analyses on active DNS measurement data
to investigate how the Russia-Ukraine conflict impacted the network
infrastructures supporting domain names under ICANN's CZDS new gTLDs. Our
findings revealed changes in the physical locations of network infrastructures,
utilization of managed DNS services, infrastructure redundancy, and
distribution, which started right after the first reported Russian military
movements in February 2022. We also found that domains from different countries
had varying location preferences when moving their hosting infrastructure.
These observed changes suggest that network operators took proactive measures
in anticipation of an armed conflict to promote resilience and protect the
sovereignty of their networks in response to the conflict.
