ICANN’s next meeting kicks off in Dublin this weekend, and U.S. lawmakers are watching to see what the group comes up with to improve its accountability. It’s a key issue the Internet community wants fixed as the U.S. government prepares to hand over its oversight of the Internet domain name system to the group. Senate Commerce Chairman John Thune and Sen. Brian Schatz — the top Democrat on the Internet subcommittee — warned ICANN of the significance of those reforms in a letter Thursday. “Significant accountability reforms that empower the community and are developed by the community are necessary for congressional support of any such transition,” they wrote.
