There must be a few CTO's feeling rather uncomfortable at their recommendation to the Board that their organisation should use Microsoft's Azure hosted computing facility. It was down again for eight hours on 23rd February from 9pm GMT. Someone in MS had forgotten to renew a security certificate. This is almost on the anniversary of a similar failure last year.
Apparently Microsoft will offer "credits" for the lost service hours. They should be showing someone's head on a platter, after paying genuine compensation.

Like most business managers I get loads of emails every day which I quickly delete after a cursory glance at the title and contents. One which caught my attention was from a company called Protecta Screen. They do a range of temporary protective sheeting for floors, walls, doors, stairs to prevent damage during construction and decorating works. It is worth noting their web address if you are likely to be involved in any office, home or data centre expansion work. It might be worth suggesting such a range of products to your contractor.

I've just been reading the specifications for the Shard building and as a designer of trading areas, I groaned a quick "Oh no!"
This iconic skyscraper is built just a stone's throw from the edge of the City of London in the borough of Southwark at the [wrong] south end of London Bridge. It is five minutes walk from the financial services centre of the City of London. The tower also has almost instant access to the London Underground Jubilee line which gives fast (seven minutes) and easy access to the finance industry in Canary Wharf. The location is well served by resilient optical network backbone services. You'd think it to be ideal for the financial services industry.
However when you read the specifications on their public web site that picture changes. The raised floor gap is only 150 mm (6 inches). That can be really restrictive in delivering power and data cabling to a trading desk. With a 2.7 metre floor to ceiling height there is little scope for changing the raised floor height. Any full size equipment cabinets will be quite cramped.
The floor loading is only 3.5 kN/M2 (73 pounds/sq foot) with up to up to 7.5kN/M2 in parts. This essentially dictates only office furniture except in a few small strong points. I've yet to see the detailed floor plans but I'd guess the strong points are not conveniently located. From their web site I can see there's also two sets of internal structural building pillars within the office areas. The pillars will restrict office/trading floor layouts.
The Standby power generators are 2 x 2000 KVA; this represents only 70 KVA/M2 when both generators are running for the office space, provided there is no draw from the hotel sections of the building or the accommodation sections. As a rule of thumb I'd say about 15 - 20 Watts of available protected power per Sq Metre of office floor, ignoring any concentrated power draw of a technology/server room.
It strikes me the space is suitable for low intensity office occupation and not the technology intensive trading floors of the financial sector. The building specification must limit the attractiveness to banking clients currently on the north side of the River Thames. When will these property developers learn to provide accommodation with reasonable infrastructure services?

New York and New Jersey suffered a lot of damage from Hurricane Sandy. Even now a couple of weeks after the impact of the damage is still effecting businesses. Apart from the obvious damage to timber frame buildings, the main damage effects appears to be:
- Loss of power
- Lack of fuel
- Results of flooding.
While I have enormous sympathy for those involved I can't but help think many of the after effects of this storm could have been mitigated or avoided if there had been some proper planning and infrastructure provision beforehand. Much of the problems seem to arise from trying to provide infrastructure on the cheap. Saving pennies has cost many more dollars. At some point in history an accountant may have shaved a few dollars from the budget for a company's infrastructure, but that same accountant will not stand up and proclaim "Mea Culpa" when the business is out of action for a couple of weeks as a consequence of those "savings". There are those who say this could be covered by business continuity insurance because it is only a 100 Year Storm. You'd trust the insurers to cover all costs and rebuild your company? Not!
Let's first look at fuel. In the case of Gasoline there were service stations which could not pump fuel because the pumps depended on mains electricity from the Utility Company. When the power went down the service stations became useless. There should be federal laws which require the provision of weather protected standby generators at service stations to provide protected power to pump the fuel.
Then there was the problem of fuel shortages. The supply of gasoline in normal circumstances is a "just-in-time" facility where the service stations depend on regular delivery of fuel every few days by tanker trucks. If that delivery service is interrupted the service stations hold only a couple of days supply and quickly dry up. The situation is worsened by panic buying by consumers. When everyone decides to fill their gas tank to the top it places strains on the limited supplies causing them to run out more quickly. It leads to rationing such as this case. This whole situation could be mitigated if service stations were forced by law to hold a minimum of 15 days stock in their underground tanks. The 15 day buffer would make fuel supplies considerably more resilient to supply shock. The finance cost of holding 12 extra day's supply is not massive.
Your organisation may have standby power generators with a 24 hour fuel supply with a resupply contract with a local fuel depot. Have you actually checked whether the fuel supplier can honour those commitments in the event of a regional disaster such as Hurricane Sandy? Flooding might prevent despatch of the trucks. I recently saw a comment on a LinkedIn forum where an organisation fuel resupply company could not pump fuel into the delivery tankers because they also had lost mains power from the utility company. You should diversify suppliers and actually check their delivery arrangements in the event of a regional disaster, don't rely on contractual obligations. If you can extend your own fuel capacity to five days you'll give yourself more flexibility in the event of a disaster.
The regional loss of power is almost inevitable in the event of a disaster such as Hurricane Sandy. Power lines will collapse and the utility company will cut power to protect substations. You should ensure access to local power generation facilities. Perhaps your own standby generator or maybe a facility shared between local businesses. The standby facility should be regularly tested with total power down scenario's. You should walk through what would happen if the basement of your building becomes flooded. A co-location hosting centre discovered this to their cost. In some cases heroic efforts such as a human bucket chain may be necessary to keep the generators running.
Lloyds - the insurance people; have written a telling paper on energy security paper. It is worth visiting their site to download a copy to read.
Flooding can strike most businesses. You may be in a low lying coastal area, a river flood plain. You may have a major water main pipe running under the street outside of your front door with the risk of pipe burst. In storm conditions damaged roofing can allow rain water leakage. If there is risk you should look at:
- the arrangements you have to prevent the water from reaching your key machinery; this might include high sill doorways, sealing of leakage points, tanking of the room floor and walls.
- the arrangements you have to quickly drain any flooding in your building. It might include pre-laid pipes, drainage sumps in equipment rooms and submersible drainage pumps.
- leak detection equipment and alerts;
- overhead drip trays which can help prevent overhead water from leaking on to sensitive equipment.
