Twitter seems to be having serious scalability issues, a malaise which plagued the otherwise popular service since its early days. twitter似乎是有嚴重問題的可擴展性，其中的弊病困擾，否則流行的服務，自成立初期天。

Could this be related to its architectural decision of adopting Ruby-on-Rails ?可這與它的建築決定採用紅寶石-對-鋼軌 ？ There was a有一個 rumor傳聞 not so long ago that twitter was abandoning Ruby on Rails .並非如此，不久前twitter放棄紅寶石對導軌上 。 While it was雖然這是 denied否認 by Evan Williams, he also mentioned that lot of Twitter code was not in Ruby on Rails at this time.由伊凡‧威廉斯，他還提到，很多twitter代碼無法在紅寶石上軌在這個時候。 Maybe they are progressively moving away from it.也許他們正逐步遠離它。

Update: Twitter down again and back up again.更新： twitter再次和備份一次。 Looks like it is going on its limit.看起來好像是對了極限。
