Senate Bill No. 1189 mandates that all municipalities in Connecticut must register a ".gov" Internet top-level domain with the Cybersecurity and Infrastructure Security Agency by July 1, 2027. This requirement applies to all towns, cities, and boroughs, regardless of existing municipal charters, special acts, or home rule ordinances. Additionally, municipalities must either redirect any existing web addresses to the new ".gov" domain or discontinue their use altogether. The bill aims to standardize municipal web presence and enhance cybersecurity.

The bill does not impose any registration costs for municipalities eligible for the ".gov" designation, but it may incur potential costs for those that lack the necessary resources or staff to transition to the new domain. Currently, 113 out of Connecticut's 169 municipalities do not have a ".gov" domain, and for those unable to manage the transition, federal grants are available to assist with the process. The bill's provisions will take effect upon passage, and its fiscal impact is expected to continue into the future, subject to inflation.
