xoserve will be undertaking the annual Gemini Disaster Recovery testing this weekend (26 and 27 July 2008).

As a direct result of the above, the Gemini service will be unavailable for the following hours:

Saturday 26 July – 04:15 to 10:15
Sunday 27 July – 04:00 to 10:00

Throughout each outage, National Grid will issue hourly ANS updates to the community with the latest System Status Information (Demand and Linepack). In addition, the ANS will be utilised to communicate any change in outage timelines, if applicable.

Due to this essential testing, there will be a loss of service to the publication of the DASD and NORD07, Capacity Daily Reports published on Saturday 26 July 2008 (applicable for Friday 25 July 2008). The DASW, Capacity Daily Report published within day will also be affected on Saturday 26 July 2008.

Subject to the return of service to planned timescales, the first Entry Capacity auctions will be run at 11:00 on both days.

Please note that upon completion of the testing, Shipper access to the Gemini service will not be affected. As a result, Gemini access should be gained using the normal operational access route following each outage period.
