I hope it gets better soon, you've got the day off so it should be fine 😆

It's not too bad if it's for few hours, but it becomes a problem if it lasts longer.

I had an UPS when I lived in Panama, for my pc, my router and also to charge the celulars if the blackout lasted long. It's just a big battery, and it prevents a PC from suddenly going out and losing your work, but it helps for a few minutes if you keep the pc on, to hours if you just let the router running for wifi.

Same, all Portugal still down. Maybe not the islands
