This makes me think of a little side project I've been chipping away at called InstaCDN. It makes it easy to minify, combine, gzip and push your css, js and image assets into the Amazon Cloudfront CDN with far-future expiration headers. It also automagically detects background images referenced in your css, and puts them in the CDN. It rewrites the css to use the new CDN image urls. It's all done through a trivial RE…

Wordwrap on you page is pretty nasty on the iPad.

Dear Pair Networks, I'd like to highlight this lesson in how to loose (or not gain) customers by randomly shutting down technology sites that serve the decision makers you wish to influence. Tom P.S. Well done Slicehost.

150K hits in 30 minutes is 83 hits/second. That's a lot to ask for from a shared-hosting account. When the traffic starts to impair neighboring sites, something has to be done. Just about any ISP will do the same thing: block the site with the surge, that could possibly make other arrangements, rather than inconvenience other customers whose traffic is as expected/usual. The detail missing so far is why Pair noticed…

Todays's logs are similar to other days. I guess the traffic is high for a shared account, but I've never noticed it being slow so I didn't think about it.

I would have been happy to respond to an email saying I should upgrade & pay more, but even after a few emails with tech support that option didn't come up.

The only limit they advertise for that class of account is data transfer, and because it's mostly just serving uparrow.gif -type files we're well below that limit.

So let's see... you're hosting a website that has gotten large; that is, it's grown to the point that it will need higher-cost services in order to meet demand. You have a chance to add a valuable customer to your client base. How best to handle this? a) anything b) except c) killing their service

Exactly

The "ask" is not that a shared hosting account support 83 hits/second. It's that the hosting company demonstrate the bare minimum of respect and professionalism in contacting the hostee ASAP when their site is being shut down due to excess traffic. This isn't bitbucket or geocities, dollars are changing hands. If you don't like running a business that makes money then by all means, treat your paying customers like they are a burden to you, they will get the hint and go elsewhere.

I was being tongue-in-cheek, but there is a real point here. As you say I doubt today was unusual for HN, it's the way Pair went from zero to shut-down. One of the things I like about the way that Joyent operate as a cloud host is that they allow you burst on shared boxes because of those times you need it. At the same time they'll let you know you need to think about buying more resources without just slamming on th…

That technology is not out there... A static site might be fun at that level and not causing problems, where as a WordPress site with super cache is fine, but then a Drupal site can only handle 1/4th of that. It currently is not really possible to track that per user in a shared environment and see who is using what resources from an individual perspective of MySQL / Apache / CPU / Mem.

Absolutely wrong. That technology exists and is being used millions of times a day at sites all over the world. DreamHost, for example, employs just such a technology for their shared hosting: http://wiki.dreamhost.com/index.php/CPU_minutes

That looks really cool. I'll be in a position to give it a go in a few months. One thing that would make me hesitate though, is not knowing what the potential pricing would be when you move from non-free.

How best to handle this?

Of course, the flip side is that leaving it running adopts an attitude of "screw all our other customers, they can eat crappy service while we kiss up to the popular guys who are chewing up everybody else's server resources". Which isn't what I'd look for in a hosting provider...

Companies like slicehost make their money on the customers that do not use their servers.
