A local power cut has interrupted the services of UK government cloud provider Memset.

Memset, an SMB supplier on G-Cloud, saw power to its data centre in Reading severed at 8.39am on Tuesday with the company claiming to have resolved the problem half an hour later.

Both primary and secondary power suppliers to Memset's facility failed. By lunchtime Memset was apologising for an unspecified number of customers still suffering outages.

"Sincerest apologises [sic] for all affected customers today if you are still having problems pls log a support ticket," Memset tweeted.

Services affected were OpenStack cloud and various dedicated and backup networking services.

Before that – and just after the firm's status page said the issue had been resolved – Memset tweeted: "Apologises [sic] for the ongoing disruption for some of our customers. We're working to restore all affected services as quickly as possible."

Memset has employed Everest Data Centres' Reading facility since October 2015.

The government IaaS provider said: "Issues transitioning on to generator power resulted in power loss to our entire estate. Currently all power has been restored to the data centre and we are working to resolve any outstanding secondary issues affecting a small number of customers."

Everest managing director Ed Butler told The Reg a "small number" of clients in Reading had been affected but would not comment on Memset.

Service was interrupted when Everest's emergency diesel generators stopped shortly after the load was transferred. Staff restarted the generators manually and power was restored to clients before 9.30am, Butler said. He promised an investigation and full report into why the generators stopped. ®
