FWIW I see this with Firefox when I route my traffic through ProtonVPN.
It could be caused by someone else's bad behavior on the VPN but I'd hazard a guess that it's more than that.

I don't think I've seen it for a week or two now but I've certainly encountered it in the past for spans where it'd occur at a frequency of maybe once every two or three days and then go away for a while.
