Some highlights:
As Dan has said the rate at which we are authorizing number of new members is about triple the normal level. We don't have a massive userbase, the current number of registered users is 2830. I don't have anything in place to track the ip-board statistics over time, that's something I'm looking at but right now I'm not aware of an easy way to get them. That said we do have some data points about the most important macro indicators of server load which is the number of concurrent users. This normally ranges between 50 and 100, with the ratio of registered users to visitors typically being around 5:1. On the morning of the MSL launch this rose to around 350 concurrent users at 6:52AM (BST), this rose a little over the next 30 minutes but we were obviously having performance issues around 07:30AM BST, and users started to see timeouts. We made some performance tweaks to address that around 7:45 and by 7:56 we had 490 concurrent users and briefly passed 1000 concurrent users at around 8:00AM BST on August 6th. I didn't keep a record of the number of users to visitors at that time but at the peak I think we had about 300 concurrent registered users and 700 or so visitors. As a comparison the largest previous spike that we have numbers for was at around 270 users for the Phoenix landing. Peak Bandwidth spiked from a typical average of 300kb/sec to something north of 6Mb/sec. This is averaged over an hour by our server stats package, and the instantaneous peaks were a lot higher. I'll update this with charts later but in terms of hits\page views\visits we peaked at 1.6 million hits, 230k page views and 40K actual visits over the course of August 6th. The data load associated with an average visit rose too, to about 5x the normal 100-200K/visit since we carried about 22GB of traffic on the 6th. Overall those numbers are about 10x our normal volume. Things have now calmed down a lot, but we're still running slightly higher than average across the board. |
