鯖落ち

• Reading: さばおち
• Romaji: saba ochi
• Kanji breakdown: 鯖 (mackerel, internet slang for server/サーバー) + 落ち (falling/dropping) → server down
• Pronunciation: /sa.ba.o.tɕi/

Meaning

Server crash or outage — when a website or online service goes down due to server failure or overload.

鯖 (mackerel) is internet slang for サーバー (server), using the kanji that sounds like 'saba' as phonetic shorthand. Combined with 落ちる (to fall/drop), 鯖落ち describes the frustrating experience of a server going down. Especially common in gaming and social media communities where server outages directly affect users.

Examples

1. ガチャ更新と同時に鯖落ちしてログインできないんだけど。 The server crashed right when the gacha updated and I can't even log in.
2. 地震のたびにTwitterが鯖落ちするの何とかしてほしい。 I wish they'd do something about Twitter crashing every time there's an earthquake.
3. また鯖落ちかよ、今日何回目だよ。 Another server crash? How many times is that today?

Usage Guide

• 鯖落ちで対戦中のデータ飛んだ。 (Lost my match data because the server crashed.)

Don't Say

• 仕事の報告で「鯖落ちしました」は避ける — 「サーバー障害が発生しました」を使う (Avoid 'saba ochi' in work reports — use the formal 'server shougai' instead)

Common Mistakes

• Not knowing 鯖 means サーバー — the kanji literally means mackerel, so it can be confusing for learners
