It's called a 'single point failure'. Poor planning.

No backup gens again, you would think their previous mistakes would have
had this sorted!


Claranet/Netscalibur also affected.

Very full information on their status page as well.

Certainly not just Plusnet.

It seems to have been a problem on one phase and probably after the
generator input so there is noting anyone can do apart from having a
totally duplicate distribution all the way to teh servers - a
maintenance nightmare just to cover a rare (hopefully) fault.

Years ago I was working on systems that had power generation and
distribution triplicated. Now some services consider simple
duplication to be too expensive.

Quote from Telehouse's website:
http://www.telehouse.net/
"Customers housing equipment at a TELEHOUSE Europe site enjoy all the
advantages of power resilience, temperature control, fire detection systems
and state of the art physical security systems, but at a reduced cost to
setting up and monitoring a facility themselves. TELEHOUSE Europe houses
most of the world's major providers giving customers greater choice and
flexibility."

Some power resilience!

Telehouse, by the way, is an independent, world-wide, Japanese-owned
company, providing ISPs with building space and security facilities for
their equipment. Plusnet is just one of their (presumably many) customers.

Even backup generators can fail. Earlier in the year our local hospital had
a power failure and the backup generator failed at the same time. In
intensive care they had to manually ventilate all of their patients for some
hours before it came back again.
Really there is only so much people can do to protect their systems.

Where I used to work, they had a long power-cut a few years ago when some
(dead) idiot in a JCB cut through a high-voltage cable as he was digging yet
another hole in the road, taking out power to most of Bracknell. The power
to the building went off (not surprisingly) and remarkably quickly there was
a noise like a 747 at take-off as the emergency generator kicked in - right
outside my window. The lights came back on again, amid much cheering, but
about 10 seconds later there was a horrendous WHOOMF and a cloud of dirty
black smoke as the generator and its fuel caught fire. It turned out that it
was woefully under-powered for the load that the building presented and also
the bearings had seized up because it hadn't been run regularly.

So any emergency generator needs to be tested periodically and must be
capable of supplying *all* the power in the building, even if only for a
short time until non-essential devices can be turned off.
