The Eurostar train service provided free wifi.
Until suddenly it didn't. Wifi was disabled in the standard seats, although it was still available in first class.
When asked why, Eurostar said that wifi was removed because of cCoVID-19. (No, it didn't make any sense to me, either.)
The wifi service has, apparently, since been restored.
