Put the onus on them
Go through the process of getting a ticket and applying for the time you were impacted. Make management allow or deny it. Management could give a blanket authorization as they have in the past, but that would require management to take accountability for their systems.
Management could have IT systems that work, but they have decided to not do that. Management has the money - biggest surplus ever yet cut the IT. Management has discretion to allow time for this and have in the past. Management is banking on you just eating the time. That would make nothing change. Management treats us like factory workers. No factory worker would flex around a line stoppage or use inferior untrained tools instead.
Management has choked out any flexibility to work on other things in a work stoppage by getting rid of training and making the docket far too small.
Nothing will change by taking all the impact of others setting up flawed faulty systems.
