The power failure that hit Redbus Interhouse's Docklands location on Tuesday morning was still causing widespread disruption Tuesday afternoon for companies that have seen their businesses knocked for six.
Mike Tims, founder and chief exec of financial news service mtn-i has spent most of the day at Redbus' Harbour Exchange facility in the Docklands and is furious at the way customers have been left trying to get their businesses back online.
So much so, he's formed a user group and has signed up 25 companies so far to lobby Redbus for change. He will be writing to Redbus in the next few days in search of answers.
Calling from Redbus' colocation facility in London he told us: "We want the chief exec of Redbus to come to a meeting and listen to our demands for a decent service. We want to hold this company to account."
Speaking late this afternoon he said some companies were still without power.
Other hacked-off punters have written to us annoyed at the lack of response from Redbus.
One told us: "We have received zero feedback from redbus in the past three hours - no-one seems to be answering phones or emails. We host ecommerce sites turning over million of pounds, pay redbus a significant amount of money for their service and haven't the foggiest what is going on."
Another said: "What a bloody nightmare. Our customers aren't interested in Redbus' problems, so I think we're going to have to switch suppliers, which is a shame - we've been pretty happy with our ISP for the past four years, but we can't be doing with this again. Power to our rack has now been down for more than three hours - it is simply unacceptable."
One owner of a small business added: "When outages like this happen it completely brings us to our knees. We have, like thousands of others, tailored our business process away from telesales on to online orders only. This is due to constant pressure on margins and therefore the need to keep overheads to a minimum so that we remain competitive."
He believes something must be done to "ensure that server companies are made to invest to ensure service levels are the highest possible."
Redbus has so far declined repeated enquiries to provide any further update on the power cut. ®
