critical infrastructure. it s so surprising for civilians to think that a substation somewhere remote could be attacked and that could have an impact on an entire city. this is a hardware attack. that s what s surprising. we send to focus on cybersecurity. that s been a big focus over the last decade. especially colonial pipeline was being seized in the past couple years. but this shows the vulnerability of anybody that simply has weapons. legally authorized weapons can conduct an attack that would affect a wide swath of the country. paj if this was done in a multisubstation tags. the parts for this are not ready available. we have supply chain crises. thank you so much for being with us this morning.
