We diagnosed the gas system. The argon, ethane and CO2 bottles
are ok (at least 400 psi on each) but the Nitrogen was empty.
We paged Jack, he said that the N2 being out can cause a main
valve to close, shutting off all gas (if I understood him right),
so he's coming in to fix the N2 and get our gases to flow again.
