It is all well and good that SIP trunk providers like Voiceflex are boasting that they are using secure data centres for their switching. But their customers lost service for an hour and 20 minutes on the 6th July 2011. They had 2 other outages in the last 12 months that I know of. This means nobody can make or receive calls and it’s very debilitating.

Apparently there was a power outage at Telecity Harbour Exchange 6/7 (HEX 6/7) in London Docklands and the backup power failed to initiate. Is the world really ready for this sort of telephony?
