Fisher Plaza East Restoration Timeline

After numerous meetings with Fisher Plaza this week, we have a tentative plan to share with our Adhost East Data Center clients. Note that this plan is still very fluid and we are meeting regularly with Fisher, as well as all of the various engineers, electricians, utilities, etc. to improve our electrical sources in the near and long terms. To this end, we are following a number of parallel tracks:

This weekend: Redundant generator-based power

1. In order to provide N+1 redundancy, Fisher will add two additional generators and paralleling equipment to the existing temporary generators. This will provide redundancy across the three central risers affected by the power outage. Until the building returns to commercial/street power, this solution will allow the building to perform maintenance on the generators as necessary without impacting service. As of July 9, 2009, we expect this work to be completed by approximately 5AM on Monday, July 13, 2009.
2. The City of Seattle has closed John Street next to Fisher Plaza for the additional generators.
3. All necessary generators are on-site.

Short-term: Temporary commercial (Seattle City Light) power and generator backup

1. We are working with Seattle City Light to create a temporary connection to their vault that will allow us to switch our main service back over to city power with generator backup.
2. The time frame for this is hoped to be less than 4 weeks and is dependent on the ability to source the proper switch-gear and other related electrical equipment. 
3. This temporary solution would follow a parallel track of building a new switch gear room and rebuilding the original switch gear room.

Long-term: Permanent solution

1. Fisher will build a new switch gear room outside the current vault and switch gear room on P2. This will allow Fisher to begin construction quickly without waiting to clear the damage equipment from the current switch gear room.
2. Fisher will also rebuild the current switch gear room which will allow for redundancy.
3. Fisher plans to add new equipment and paralleling equipment to power up the building’s four generators together.

Fisher emphasized that their vendors are locating equipment and designing the new plan as quickly as possible. However, they are expecting several months until full restoration. Once they have a firmer timeline we will share it with you.
