It’s certainly a relief to have an apparent explanation for the weirdness I’ve been experiencing! I thought it was my home router or WiFi or something, but then I experienced the same problems at my partner’s house, so I thought maybe it’s just a problem with some websites I frequent or some common internet infrastructure. But we both have AT&T internet, so this must be it!

For me, the problem has mostly manifested as web pages failing to load or appearing to be loading forever. Generally when I refresh the page would load quickly as expected.
