前幾天 Gmail 可以正常運作，但一直收不到信的問題由官方發公告出來解釋了：「More On Gmail’s Delivery Delays」。
官方宣稱，這次的問題出自於兩個獨立的網路同時掛掉，造成 Gmail 的收信處理能力大幅下降：
The message delivery delays were triggered by a dual network failure. This is a very rare event in which two separate, redundant network paths both stop working at the same time. The two network failures were unrelated, but in combination they reduced Gmail’s capacity to deliver messages to users, and beginning at 5:54 a.m. PST messages started piling up.
