Recently, I was called about a SQL Server outage. Here were the facts:
- 3 servers were impacted
- The servers could not be pinged
- The servers would not allow users to login with domain credentials directly via the console.
- All the servers were on the same subnet in the same rack behind a firewall
- Other servers in the same rack were up and responding to requests
- No changes have been made for months to any of these servers
An hour of time was was spent trying to troubleshoot this as a SQL Server issue, when it was clearly not. Do you know what the issue was? The answer is in the comments.

The firewall had locked up and was not letting traffic flow through it. The redundant firewall was not configured correctly thus it did not take over for the primary causing downtime.
