brand their stations by call letters and channel numbers rather than their network affiliation. Move to Vermont On June 12, 2018, WPTZ announced it was moving to a brand new broadcast facility in South Burlington, Vermont, in a building that contains both a data center for Keurig Green Mountain and the main offices of Ben & Jerry's. The move took place in July 2019, when WPTZ began broadcasting newscasts in high definition. WPTZ continued to maintain the Television Drive facility for several months in Plattsburgh as a secondary studio, while closing a now-duplicative and smaller bureau in Colchester, Vermont. WPTZ later relocated the bureau to a new location at 308 Cornelia Street in Plattsburgh, taking over the former Glens Falls National Bank branch and renovating the building to become its new secondary studio in the summer of 2020. 2019 antenna fire On November 19, 2019, WPTZ, WNNE and CBS affiliate WCAX-TV (channel 3) were knocked off the air by a fire at their combined antenna at the transmitter facility. The cause of the fire was unknown. The outage affected over-the-air and satellite viewers; cable subscribers continued to receive the three stations via direct fiber feeds, while Vidéotron in Quebec temporarily replaced WPTZ with Detroit NBC affiliate WDIV-TV. WPTZ-DT2 In September 2006, WPTZ established a daily web video forecast as part of a major revamping of its website. The feature, called "Weather Plus Update", introduced a logo showing WPTZ/WNNE offering NBC Weather Plus together as "5&31 Weather Plus". Starting in October, its studios in Plattsburgh underwent extensive renovations. During that time, its broadcasts were from a temporary set while the construction took place. While the studios as a whole were being upgraded, the weather department underwent the most change. In advance of the launch of NBC Weather Plus, the weather center was expanded to make room for new combined WPTZ/WNNE weather graphics and logos. The remodeling was completed by late-November. WPTZ launched Weather Plus on a new second digital subchannel on November 15 after debuting a new digital signal from Mount Mansfield a day earlier. The service was never offered on WNNE's digital signal even though this had been airing since July 20, 2005. On digital cable, WPTZ-DT2 was carried on Comcast digital channel 169 (serving the Upper Valley), Telecom digital channel 305, and Time Warner Cable digital channel 854. It was never offered on legacy Charter systems in New York
