comment All my emails to Yahoo!, Hotmail and AOL are going to Spam, though I've implemented every validation method (works for Gmail though)
Just to be clear - Sender ID is not the same as SPF. They are different.

comment Apache not responding in amazon ec2
From inside the EC2 instance, does 'telnet localhost 80' work (assuming you're back to running Apache on 80) ?

You need to update your question with your AWS security group configuration so that we can see if something's wrong in there.

You will need 443/TCP from 0.0.0.0 also if you have HTTPS on your site.

comment How to automatically update nginx upstream server list when aws ec2 hostname changes or increases?
I think you can combine AWS autoscaling notifications (delivered using SNS) - assuming it returns the host name of the newly created/terminated instance - and one of the third party nginx APIs to update and reload your nginx configuration. Sorry for being vague - I'm not very familiar with the autoscaling API.

The question is clearer now, in its intent. I wanted to vote to re-open, but I don't see an option - guess I don't have enough rep yet.

"It is REALLY unlikely that EC2, or HP, or IBM will go down" - This "unlikely" thing has bitten us many times. Everything fails.

comment How to automatically update nginx upstream server list when aws ec2 hostname changes or increases?
You need to remove "autoscaling" from your question. Autoscaling is an AWS term. I think what you mean is you want to automatically scale (horizontally), by adding more upstream nodes to your nginx acting as an LB, and you are asking how to automatically modify your nginx configuration when upstream nodes are added/deleted/modified. If this is so, please edit your question accordingly.

comment Opening ports in EC2
Go through this checklist - 1. Where have you opened the port to? Public? 2. If yes, try telnet <ec2 instance's IP> 9160. If it connects, your port is open. If it does not, you've either not given the correct source (group, CIDR range) while opening, or there's a firewall running on the instance.

comment How do you administer your EC2 Linux boxes?
"I use the standard package management tool like APT or YUM" - apt-get/yum always picks the latest. How do you manage if you have to install another version of the package (made necessary by the particular needs of your application)? Or have you never faced this?

comment Clever nagios alert methods
If it works for you, then great. Disclaimer - I've no experience with pagers. But do you really care that it's 'uncool' - as long as it works and gets your job done? +1 for using what works, -1 for self-deprecation :)

comment Getting Apache to redirect all urls to a different host
@Prix - sorry, my bad. It is enabled. The LoadModule entry is present, and so is the .htaccess entry (I assume that's what you meant). Thanks for the help.

Thanks, but it doesn't. Am suspecting something with my Apache installation now.

Thanks, but it doesn't - in fact, this is the most common example I've come across.

comment Which CDN do you recommend for good organization of files?
They do have an API, but they do not offer official support for developing in it. Also, they don't support gzipping of static content- which is a real negative.
