IT incident on the airport

Few days ago had first hand experience of the passport control system collapse at Boryspol. The person in from of me passed control with what I consider normal control speed. Than it was my turn. The passport official took my passport. Than started to turn it's pages. From the back to the front. Than from the beginning to the end. I have a thick passport. With many stamps. Often at the passport control officials look through it and than examine visas and stamps. Few times I was asked why I have such a big passport. 
But this time the young man looked uncomfortable. Than started to turn pages again. Than he pushed some keys. After standing for some time I asked him if something is wrong with my passport. He smiled and answered "system is down". Next few minutes everyone was a bit upset. Together with other queuing passengers  I got even more upset when the official  left his booth. But quickly there was an explanation: all officials went for the lap tops to process passports manually. Altogether we all waited for about 30 min that officials start manual passport processing. I asked if collapse of the system happens often. The answer (of course) was "not". That was the first time. I was surprised how well organized everything was. As queues of people for passport checking got longer - more officials came and started manual passport checking. Passport officials also informed airlines about the delay. To my knowledge only one plane (to warszaw) was significantly delayed.
I was impressed how well passport control managed the IT incident.
