§ Mr. Lidington
To ask the Parliamentary Secretary, Lord Chancellor's Department how many transactions per second the Internet service provider responsible for the 1901 Census on-line service could provide at the time the service was suspended; and how many transactions per second it will be possible to provide once the programme of enhancements has been completed. 
§ Ms Rosie Winterton
QinetiQ Ltd, who are responsible for the delivery of the system and service, designed and supplied a system which was to support 18,912,000 static page impressions and 4,800,000 dynamic page impressions for a peak of 1.2 million users per day. This equates to an average of approximately 274 page impressions per second. When the system is again available it is intended that it will be able to provide at least these levels of performance and be considerably more robust. Testing of the updated design and configuration is still continuing to confirm this, before the service is resumed.
