When trying to refresh the site a few minutes ago, I got a bad gateway error screen. This would’ve been about 6:20 pm EDT on the Samsung Internet browser on my Android phone.
Which is almost 7 years old, FWIW, so this may well be a device blip and not a site blip. But I wanted to mention it just in case. I was able to open the site and log in on the same device using Chrome, and shortly thereafter it was fine on Samsung Internet, which is the browser I’m using right now.
