comment If DNS Failover is not recommended, what is?
Just when I'm getting excited to other methods like anycast I get this. LOL. I guess the big question is, will DNS failover work 100% in the future? Are all browser manufacturers required to follow this failover mechanism or is it optional? One of the biggest argument is we can't expect clients to behave as we expect it. But if every browser manufacturer is going to fix this then this is definitely cost effective than anycast implementation.

Does this mean I need to have the same IP in datacenter 1 and datacenter 2? If yes, how do you actually do that?

comment Are self Self-healing Cloud and Traditional Failover Boxes basically the same?
It should be standard practice I agree. But by default meaning when I purchase cloud hosting, it is by design that it will reboot to the next machine if the current has become problematic. Now if I purchase a VPS box, it's just that, one box, it doesn't come with load-balancing or failover, since those are optional setup. So in other words VPS w/ load balancing and failover isn't sold as standard in the market.

You are right. I confirmed with a cloud provider that there is around 5 mins downtime to boot to another available machine so it isn't instantaneous as it was perceived. I guess the only credit it deserves is at least it is done by default while true instantaneous failover requires custom setups.

From what I understand in what your saying, in terms of high availability, traditional HAproxy failover is faster than cloud rebooting to another machine? And in terms of scaling new hardware, cloud still requires some downtime whereas in traditional failover you can setup additional load-balanced boxes without any downtime?

Thank you for the comprehensive answer.

comment Suggestion on email server with “infinite” disk?
@Massimo - Precisely why I ask this question hence the title "suggestion". If it's still unclear I need an idea on how to setup an email storage server which can increase infinitely as the need arises. I am not the one who's actually gone set it up but I need to tell them that according to Serverfault "this" is the optimal way to achieve this.

comment Suggestion on email server with “infinite” disk?
@RobMoir- "they just have very high limits that they increase frequently", this is exactly what I mean. I am looking for advice on how to achieve that specifically for email storage use.

@Sirex I am under the impression any reputable hosting company is able to provide this or is it really that special?

@dusan.bajic - I understand nothing is unlimited but I heard you can setup a cluster of servers and add disk as you. Is this a viable option?

comment Suggestion on email server with “infinite” disk?
@Iain - I was hoping this topic will not be closed and I tried to be technical by saying Cloud or Raid. But really I am looking for suggestions on the best way to go about this as I think Serverfault is the best place to ask this kind of questions since this deal with Server infrastructure. If you think this belong somewhere else, where can I ask this?

I understand, that is why am I looking for suggestions on the best way to go about this. The company has a budget so money won't be a big issue so long as it's the best way to go.

comment Best Practices in Speeding-up DNS Propagation
@Alnitak You mean update the IP address of xxx and yyy so they point to the same IP right? The problem is the other nameserver is on a shared host (ns1.dreamhost.com) so I am unable to edit the IP.

comment Best Practices in Speeding-up DNS Propagation
If I ask my users to use Google's public DNS, would this help them? Because right now I am on Google's public DNS and it's pointing to the updated nameserver. I am not sure though if it's working for all who uses Google's.

comment Best Practices in Speeding-up DNS Propagation
Thanks. So you mean setting the TTL low is just a best bet since some ISPs don't really follow it, and that in reality, it's pretty much a sit and wait game regardless of my preparations?

comment DNS Round Robin: Multiple Nameservers VS Multiple A Records?
But isn't using HAProxy alone will still depend on TTLs, therefore will result with the browser waiting to know the next server IP until cache expires? If that's the case then it will be longer than simply having multiple A records. Perhaps a combination of both HAProxy + multiple A records is the best approach?

comment “Simple” Failover to a Geographically Separated Server?
Thanks however looks like Akamai is quite expensive. Can you recommend a service that provides your second suggestion? :-)

I see, Ok I was Googling for a couple of CDN providers and can't seem to find one that offers even plain HTML serving as a main host. Can you recommend a provider which does whole-site?
