Unscheduled downtime – Friday 8th May 2015
At 2:07pm on Friday the 8th May 2015 for three minutes and again, at 2:19pm for nine minutes, ending at 2:28pm, a failure of equipment at our hosting provider resulted in the NHS ePortfolios website at http://www.nhseportfolios.org becoming unavailable/unresponsive to some users.
During this time, users would have encountered disruption / errors as our systems transferred users away from failing devices to other, still functional, devices.
At 2:24pm, for four minutes, the NHS ePortfolios website was online, but user requests were being serviced by only one of three devices that are normally responsible for this task. At the time, around 600 users were making approximately 2,500 requests per minute. Response times from a single device would have resulted in an unacceptable user experience at this time.
Intermittent outages affecting a single device continued to be experienced until 3:23pm.
Shortly after midnight, a configuration change was performed by our hosting provider and disruption has subsequently not recurred.
