Why do people have their eggs in one basket? More specifically, whenever hosting comes up on HN, it's always DO vs Linode. Why not Zoidberg^Wboth? In the age of DevOps, it's not hard to configure different providers . I have been using Linode and DO for a while now. I noticed DO go down last week, checked my site, and it was UP because it was being served via Linode. I flinch every time I hear someone say to me that…

How do you do this on the DNS layer? Very short TTL and switching on failure detection? Do you use both providers at the same time when both are up via DNS round robin or similar?

There's nothing stopping you from adding multiple A records for a domain. In fact, that's what a lot of people do:

  dig a www.google.com

  www.google.com.         300     IN      A       74.125.237.178
  www.google.com.         300     IN      A       74.125.237.177
  www.google.com.         300     IN      A       74.125.237.176
  www.google.com.         300     IN      A       74.125.237.179
  www.google.com.         300     IN      A       74.125.237.180

Browsers these days will resolve and try each one, on a first-come-first-served basis. If one fails, it will try the request on the next server.

I find that surprising. Linode support never contacted me regarding resource usage. Not even when one of the servers has been under DDOS. I contacted them first notifying of such event. And that was it. I agree with harpastum. I think you're confusing automatic email notifications based on your own settings with Linode support. I feel like you have to seriously abuse their infrastructure to get them to contact you. D…

http://i.imgur.com/UCPWdBq.png I was not confusing automated emails with direct contact from Linode support. I fully understand and can appreciate the need to be a "nice neighbor" in a shared environment but what baffles me is: 1) Linode doesn't have the capability to actually enforce any sort of quota or limit. It's 2014, there's been numerous advancements in the area of virtualized servers in the past decade. cgrou…

Thanks for the answer.

1) I don't know enough to talk about resource limiting that Linode might do. There might be a reason they don't want to or can't use it with their infrastructure.

2) I agree, they could publish some guidelines for resource usage, but this is hardly baffling. I'd guess most of the customers just don't hit this problem, so there's no need to list all of the limitations.

If you have your own IP-space you can use BGP to route IPs to different locations.

If you're relying on DNS then short TTLs are pretty reliable, but there can be extended outages due to erroneous client-caching.

If you'd used their servers for a bit longer, you'd have plenty of trouble. Linode is notorious for dreadful security practices. Their main ColdFusion app (yes, really) has been hacked on numerous occasions, including at least once incident that involved customer data loss. Linode dodged the issue and didn't tell their customers until badgered. I can agree that DO isn't suited for production apps, but Linode isn't ei…

Is there a better alternative you would suggest? While Linode has done better than DO, that fiasco left me feeling somewhat uneasy as well.

There are a great many VPS and server providers out there. I've had good experiences with gandi.net, Rackspace, moln.is and pgrmr. I've seen Ramnode and Lithium Hosting get a lot of praise. You could also use AWS if you don't have any ethical objections to using Amazon products.
