Access card failures at work

Yesterday my workday started unusually. I arrived at 8am but it turned out that since 7am they had been trying to get the campus access card system to let people in. After 9am I was sitting outside at a picnic table with some coworkers and by 10am I was on my way back home. Sometime after 11am access to my office's building was restored, then the energy utility supplier hit campus with a series of overvoltages.

Later in the afternoon there were still access system glitches occurring. Fortunately I had brought my work laptop home for the weekend and campus now has good wifi coverage so I was able to get useful work done early on from outside my building then later from home where I was safe from being caught on the wrong side of an ornery inter-zone door.

This morning I am heading onto campus a little later than usual, when there will be security staff available to check access cards manually on our way into the building complex.

Update: Indeed there was a guard to check my badge and let me pass; I have been able to reach my desk today.
