Opera Server Errors - Feb 17 2006
Click for a larger version

This is a classic display of the “run in circles, scream and shout” problem identification and resolution process.

One-half of the Opera Web servers at are not responding.


They have three separate public IP addresses, and it is clear that behind those IPs are many more NAT|VIP machines that respond to requests.

Did I mention that one-half of the machines at all three IP addresses are not responding to HTTP requests?

Has anyone at Opera noticed this?

Sometimes I feel like even the echoes aren’t listening anymore.
