Facebook, Messenger and Instagram are down. Twitter, Voxer, Signal, Gmail and Telegram seem to still be working. It seems like a good time to think about communication networks and preparedness if this disruption isn’t easily resolved. My impression is that there is some “routing” malfunction in the coding that makes the website unusable. And also that Facebook employees are not able access company buildings with their badges. Is it a hacker attack, accidental, or something else? I don’t know, but I found this analysis on Twitter which seemed helpful to me. For now, I am glad I have this page and those other still-functioning apps to communicate. Breathe, and be well y’all.
