In Newscast issue 640 and 643, we advised BSC Parties of the planned outage on 2 April and 3 April 2017 to facilitate the relocation of all BSC Central System hosted from datacentres based in Central London to South Wales. The planned downtime will impact both BSC Central Systems applications and the ELEXON Portal. The timings are as follows: BSC Central Systems applications – there will be planned downtime between 20:57 (BST) on Sunday 2 April to 09:15 (BST) on Monday 3 April 2017 ELEXON Portal – there will be planned downtime between 09:00 (BST) on Saturday 1 April and 09:15 (BST) on Monday 3 April 2017. How will I be affected? During the period of planned downtime for the BSC Central Systems applications, you will be unable to submit contract notifications to the Energy Contract Volume Aggregation Agent (ECVAA) service or receive communications from the ECVAA. Parties may wish to arrange for their Agents to submit all contract notifications in advance of this planned downtime in order to reduce the risk of missing Gate Closure.   The BMRS website ( will be unavailable and will not display market data, however it will be updated after the downtime following the processing of any backlog of files. In addition, Parties will not receive TIBCO or Data Push messages, however, these messages will be sent after the downtime. During this planned downtime, no data will be sent to ENTSO-E Transparency Platform from BMRS.   The ELEXON Portal will also be unavailable for a period of planned downtime which begins prior to the planned downtime for the BSC Central Systems applications, so any REMIT data which are submitted through the ELEXON Portal will not be published by the BMRS website ( until after the downtime. Important pre-requisite checks There are a few pre-requisite checks that BSC Parties should undertake prior to the outage to ensure their use and access to BSC Services continues. You should ensure all access to the following services is, where possible, by use of Domain Name Service (DNS) and not by direct internet IP addresses (as these will change during cutover). Domains affected during the migration are:, Those BSC Parties that do not use DNS to access the Services, opting for direct internet IP address access, must ensure that following the outage the new IP addresses listed below are used, and outbound firewall access from your networks is set-up to the new internet IP addresses:    DNS service -  New resolving IP address post outage - - - Note: BSC Parties opting for direct internet IP address access that do not update their systems to the new IPs will not be able to access the services detailed above from 3 April 2017.   Contingency date  The testing of the migration process and the ability to run BSC Services from the new datacentre location has progressed well, however, we feel is it prudent to have a backup date and have agreed a contingency outage for Sunday 23 April 20:57 (GMT) to 09:15 Monday 24 April 2017. We will formally advise BSC Parties via ELEXON Circulars should we need to use this contingency outage. For further information or clarification, please email Paul Pettitt, Head of Project Delivery.
