Google 在 9/30 正式推出 縮址服務, 後面是隨機產生的四碼小大寫+數字, 四碼小大寫+數字的排列組合只有 62^4=14776336
假設每秒有十個縮址產生, 一天用掉 864000 個組合, 17.1 天就會用完所有四碼的組合,
為什麼到現在都還沒用完啊, 真神奇!
本來猜是不是自動會移掉太久沒人使用的 Link, 但是 Help 這頁 有提到 short URLs are randomly generated, and the mappings of short URLs to long URLs are publicly accessible. Additionally, the short URL to long URL mappings are:
* Immutable - once created by you, no one else can change them
* Irrevocable - once created, they do not expire. Note, however, that Google reserves the right to remove any short URL, for example for spam, security or legal reasons
所以縮址基本上是不會過期的 的服務, 早在 2009 年 12 月左右就開始運作了, 到現在還沒有用完四碼,
表示使用率不是很高, 平均每秒不到一個縮址產生.
(每秒一個縮址產生, 171 天就會用完四碼的組合)

2010-11-03 Update: 就在這篇文章後沒幾天, 現在新產生 URL 變成五碼了
