Questions:

1. Power Failover plan?

2. IP Failover plan?

3. Bandwidth? Pipe?

4. Kind of web servers? How many?

5. Plan B in case network/servers go down?

 

Answers:

ok here goes:

Power Fail-over:
- all our servers have redundant power, storage and cpu

IP Fail-over:
- we are equipped with redundant load-balancers that balance the load and ensure working status of all web and storage servers

Bandwidth:
- we are on a burstable 100mbit pipe with the ability to upgrade to 1tb on the fly.
- we use Limelight Networks to distribute our media, which is like an infinite pipe-stream across the globe. Limelight serves content for companies like Microsoft who outsource their content distribution.

Web servers:
- we run about 95% Dell Poweredge 2950, 2850 and 1850 servers
- as mentioned, all are equipped with redundant power, cpu and RAID storage

Plan B:
- head for the bomb shelter in the basement: We're hosted out of the central Canadian internet hub at 151 Front st. http://www.151frontstreet.com
- there are about 10 different ISP's interconnected into this world-class facility ensuring redundancy at every level

Hope that answers your questions
