A few hours ago, 2/3 SkyFeed Query Engine servers stopped fetching new posts from the database. So about 2/3 of feed requests did not show the most recent posts. Should be fixed now, I suspect that it was caused by them getting stuck after the short Hetzner vSwitch network maintenance earlier today.

Hey SkyFeed users, Hetzner is experiencing a vSwitch outage which affects the SkyFeed query engine servers hosted in Finland. I'm re-routing requests to Germany now so feeds should still work, but they might be a bit slower to update than usual! status.hetzner.com/incident/1db...

[ざっくり和訳:SkyFeed不具合の原因について]

数時間前、SkyFeedのデータを検索するためのサーバーの2/3が、新しい投稿の取得を停止。そのため、約2/3のフィード取得のリクエストで、最新の投稿を表示できませんでした。

今日未明(現地時間)に行われたHetzner vSwitch(ネットワーク関連のツール)のメンテナンスの後、サーバーが動かなくなったのが原因と思われます。
