Can't Route to Most of Internet

Today, all of google's services went down this morning, for me. I visited their status page, and they were all down, with a noticed about it. About half an hour later, they were back up. Right now, it's 19:08-0500, and I can suddenly only reach a handful of servers. All of google's servers work. Most others don't. I can't reach github, I can't reach the tor directory servers, I can't reach most mirrors to perform system updates, but I can reach a handful of system update mirrors. I'm getting "no route to host" for most ip addresses. A decade ago I would have been excited to diagnose this in detail, but nowadays with severe schizophrenia it is just making me way more confused.
