- enwiki was down at 10:44 (and still a bit slow now)
- https://downforeveryoneorjustme.com/en.wikipedia.org indicated "It's not just you! en.wikipedia.org is down."
- https://downforeveryoneorjustme.com/commons.wikimedia.org indicated "It's just you. commons.wikimedia.org is up." but Commons was at least slow.
As with T279809 in the past, the outage was too short for me to run more tests.
