Paweł Kadysz I live few kilometers outside the town, so it's a bit different here. Sometimes they just turn the power off during storms, even before the storm actually happens.
I don't have UPS, just the battery in my laptop. But UPS might actually be a good idea. I'll look for one and maybe buy it next week. Thanks for suggestion! ;)
Satoshi T I knew about huge storm from @Michał 's pic , but I didn't think infrastructure was down... do you have UPS or another protection system?
