What I've noticed over the past months is weirdness in websites, things not working like they should, very slow navigating around. Hilton, for instance, won't load my info if I'm using Chrome. Nothing else concrete, just overall weirdness in travel sites. I suspect that the people who usually keep these little things under control (and there must be a million little bits that need adjustment on a website like Hilton's every week) are not able to give the usual amount of care due to the virus ... working from home, curtailed hours ... who knows?
