For those of you not awake at an appropriate time equivalent to 5.35 am GMT, here are the changes made to the Heartbeat Blog entry explaining Skype's two day outage last week.

According to the Skype website, the blog post was edited at 11.45 am GMT, with changes made to the first two paragraphs.

Just for the record, here are the changes. [my emphasis]

Paragraph one was altered to put the blame squarely on the Windows Path Update. The Original text read: "On Thursday, 16th August 2007, the Skype peer-to-peer network became unstable and suffered a critical disruption. The disruption was initiated by a massive restart of our user's computers across the globe within a very short timeframe as they re-booted after receiving a routine software update."

This became "On Thursday, 16th August 2007, the Skype peer-to-peer network became unstable and suffered a critical disruption. The disruption was triggered by a massive restart of our users’ computers across the globe within a very short timeframe as they re-booted after receiving a routine set of patches through Windows Update."

Perhaps the company didn't want to appear to be blaming Microsoft, but then decided it might as well.

It also, at the same time decided that maybe there wasn't all that many reboots. The change to the second paragraph was to remove the word "abnormally" from this sentence.

"The abnormally high number of restarts affected Skype's network resources. This caused a flood of log-in requests, which, combined with the lack of peer-to-peer network resources, prompted a chain reaction that had a critical impact."

It simply became "The high number of restarts affected Skype's network resources. This caused a flood of log-in requests, which, combined with the lack of peer-to-peer network resources, prompted a chain reaction that had a critical impact."

Not important I'm sure, but an interesting couple of edits to a document that took two days to post.
