The Boardgames Stack Exchange question How would an instant or sorcery with an effect that targets work with Feather? became a Hot Network Question three times, according to its timeline:
All three events have the exact timestamp (19:14:39 UTC - shown when you click the 'toggle format' link or upon hovering) so it's probably a race condition or something.
It's not a unique case; this SEDE query finds instances on a single site, and this cross-site query lists all occurrences in the network (currently 201).
