comment Specifying image dimensions to improve browser performance
Your question is about performance, so the addition of any sizing elements that prevent reflows/repaints will speed up page rendering. However if what you render is ugly -- what's the point. See bybe comment about using JS to serve smaller sized images on smaller viewports. That's a better solution if quality is more important -- and it could be faster but you would have to test.

I am not so sure that you do not use width/height information but that the information is relative to the viewport?

comment Specifying image dimensions to improve browser performance
Actually, most current browsers process rendering information from HTML/CSS in parallel. These are then fed into the rendering engine to go onto painting. If you properly specify images and other layout, the page layout can be ready while other non-blocking assets are downloading.

comment Google PageSpeed, optimizing Google's own elements
I do not place too much emphasis on Google's scores or important or non-important rankings. The real question is does implementing their recommendations improve start-render and page-complete times. If not, then you are chasing phantoms. I've seen cases were applying their recommendations actually decreased site performance, so be sure to measure properly using browser based testing.

comment Understanding the maximum hit-rate supported by a web-server
If you need to crawl the site and they don't mind you crawling, contact them. Every site has different rates. They may not mind if there's something in it for them.

comment IP blocked because: (smtpauth) Failed SMTP AUTH login from - can someone explain?
Can you please update your question with more details about your server. What OS, mail server and hosting control panel? This will help give a more precise answer. Also have you checked your server's authentication logs? If so, provide examples - you can scrub out the ips or other personal information.

comment Ranking hit after site migration
Ever case is unique but after any major site change I've done, I have seen it take 2-4 weeks to rebound.

comment HostGator hosting account and DNS servers
DNS caching is highly problematic with some ISPs. There are DNS caches at the browser level, OS level, your router/gateway and ISP. You may want to check google's DNS by dig against @8.8.8.8. If they have the new IP, update your computer to use Google's DNS service.

comment Dedicated IPs for each ccTLD
@closetnoc Do you have a reference or study that shows how using a dedicated IP impacts domain trust? I don't think this is even considered any longer - except maybe spam cases.

comment How to verify real people?
If I understand correctly, you are trying to validate identity? That is you want some person that signs up as band X on your site to be legally responsible in some way for band X. Is that the goal?

comment Switching to HTTPS - redirect question
Be sure to test that your SSL certificate works with both www.domain.com and domain.com. If you ordered a SSL certificate for only domain.com users will get a browser warning for https://www.domain.com/.

comment What's the minimum age for a Cache-Control header with Akamai?
I recommend you ask Akamai. This likely varies with the level of service you use. Also, instead of breaking caching, you may want to consider versioning your static assets. You can then use micro-caching or ESI in Varnish for your HTML.

comment Are there any disadvantages to Cloudflare’s “Flexible SSL”?
I've updated my answer. There are actually 2 locations which SSL can be used. The FlexibleSSL negates the need of an SSL certificate on the origin server. CloudFlare will be providing the SSL certificate for free on their caching servers. So we are actually both right (or both wrong depending on your perspective).
