Wikimedia site outage, 6 August, 2012

Posted by CT Woo on August 6th, 2012

Wikimedia sites experienced an outage today that started at about 6:15am PDT

(13:15 UTC). Except for the mobile site, the sites were brought back up by
7:18am PDT (14:18 UTC). Mobile site services resumed at about 8:35 am PDT

(15:35 UTC). 维基媒体在6:15PDT(见说明)(13:15 UTC)开始暂时停工。除了行动版，其他站点都在

7:18am PDT (14:18 UTC)恢復了運作。手機板則在8:35 am PDT (15:35 UTC)恢復運作。

At about 6:15am PDT, we were alerted to a site issue and our team found severed network connectivity between our two data centers. Upon checking with our network provider, they informed us that the outage was caused by a fiber cut between the two data centers. 在6:15am PDT时我们的团队被通知网站出了问题，并且我们的团队发现有两个我们的数据中心之间的连接断掉了。在和我们的网络服务供应商检查后，他们告知我们这次停工是因为两个数据中心间的光纤缆线被切断的缘故。

The data centers — one in Ashburn, Virginia and the other in Tampa, Florida

— are connected by two separate fiber links (for redundancy). While Ashburn
serves most of the traffic, it needs to talk to our Tampa data center for

backend services (e.g. database). 这两个数据中心－一个在维吉尼亚的阿士伯恩另一个在佛罗里达的坦帕－是由两个独立的光纤缆线联系的（为了备用）。虽然阿士伯恩数据中心提供大多数的流量，不过他仍需和坦帕的数据中心作联系以获得后备服务（如数据库）。

We do operate two 10-g separate fibers between the data centers. We are now working with our network provider to determine how and why we were impacted

by that fiber cut when we are supposed to have redundancy in our network.

We are still waiting for their full report. 我们有两个10-G的光纤缆线来连系这两个中心。我们现在正和我们的网络服务提供商一起试图找出破坏程度以及为什么导致光纤断讯，在我们有多余的网络联系的情况下。我们正在等待他的全面报告。

The team worked around the outage by rerouting traffic to Tampa, bypassing the

Ashburn site. Connectivity was restored at about 8:35am PDT to one of the

provider’s network links. The second link was restored at about 11:30am PDT (18:30 UTC). However, we have not reverted traffic back to Ashburn yet until we are comfortable with their fix. The switch back to Ashburn from Tampa should

not be apparent to users.

团队现在绕道于阿士伯恩中心，并把流量改道坦帕中心来恢复运作。8:35amPDT时透过一个网络服务提供商给的网络线路，连系恢复了。然而我们尚未恢复阿士伯恩中心的流量，在他们的修复能使我们可以高枕无忧前。对各位用户从坦帕切回阿士伯恩的操作并不会有显著的影响。

说明： PDT是太平洋日光时间，UTC是世界标准时间 PDT换算成中原标准时间需要加上15小时 UTC则是加上8小时

也就是停止运作的时间是约21:15到22:18左右不过前面是发现的时间，也许实际停止时间会比较早
