Equinix has claimed responsibility for a BT outage that led to around 10 percent of its customers experiencing problems their internet connections.

BT issued apologies to its customers, who experienced major problems with broadband as well as banking services.

Equinix, the data centre company, admitted that the outage had occurred at one of its sites in London. In an email seen by the Register, the company admitted there was a power issue with a UPS system at its LD8 site in the Docklands.

 “Some BT Broadband customers have reported problems accessing websites this morning. Sorry, we're aware of a problem & working to fix asap,” the BT Care account tweeted.      

According to the website Down Detector, reports came in from London, Birmingham, Manchester, Milton Keynes, Nottingham, Leeds, Sheffield, Bristol, Liverpool, and Leicester.

The website said that the peak for reports of outages was between 7 and 10 AM.

However, this specific fault mainly affected customers in the south east.

The outage occurred at a former site of Telecity, a data centre company that was acquired by Equinix in May 2015, derailing a merger with the Netherlands-based Interxion to create one of the world’s largest data centre companies.

A BT spokesman said in a statement: "We're sorry that some BT and Plusnet customers have been experiencing problems accessing some internet services this morning.

The statement said this had “been caused by power issues at one of our internet connection partners' sites in London.”
