EMIS's HSSI report says the connection was restored automatically when the switches recovered, and the care record server was restarted. "We have opened an incident with HP, the suppliers of the equipment, to investigate why a pair of high availability switches failed simultaneously," the report says. EMIS Group chief executive Sean Riddell said the switches were set up to have "no single point of failure", but for some reason two switches failed causing an "inelegant close down". The incident did not cause any data corruption. A GPSoC supplier report for November also shows that the following systems are SCR compliant; EMIS LV, TPP SystmOne, iSoft Synergy and INPS Vision. Eighty per cent of English practices use these GP systems. A CfH spokesperson said both EMIS Web and Microtest were developing SCR functionality and plans indicated that both systems should achieve full roll-out approval for SCR this summer.
