Well, this was a fun day. Nothing like having to climb up and down seven flights of stairs in pitch dark a few times and keeping yourself entertained with a hand-crank FM radio, portable solar panels and a Kindle.
Mobile networks saturated quickly and went out after a few hours (around five, short of the eight I expected), power took around nine hours to be restored and fiber service is still mostly out, so tomorrow is going to be an interesting day as I try to bring my homelab back online (but at least the Portuguese grid can still be self-sufficient, even if they had to do a black start).
Still no root cause, though, other than the obvious fact that the Spanish grid went unstable and took out ours (because it’s cheaper for us to import their power, and because European power grids tend to be interlinked).
Loads of discussion on Hacker News if you’re so inclined. Me, I’m going to bed.
Update: Here’s a breakdown of what Internet traffic looked like. The mobile traffic held on for longer in other parts of the country, apparently.
