Andy,<br><br>Yes, I would agree with your analysis. I&#39;ve just seen a failure at another site where both disks in a RAID configuration failed. Our sites were down for 24 hours while we re-constructed the sites and restored data.<br>
<br>So, depending on the net cost and specific details, there could be some benefit to IP failover.<br><br>BTW when I mentioned that another provider would be beneficial ... I was not hinting that BitFolk was not a great provider! :-)<br>

Hi Sandy,<br>
<br>
It&#39;s important to weigh up the common faults against the cost of<br>
protecting against them. The most common failures at BitFolk I think<br>
have been:<br>
<br>
a) Server hardware failure<br>
<br>
b) Power outage to rack / suite<br>
<br>
c) Network outage / DDoS<br>
<br>
I&#39;m not sure but in terms of length of outage I think the above<br>
ordering is probably correct as well.<br>
<br>
Having a VPS on another node helps in the case of (a) and maybe also<br>
(b) if the other node is not in the same suite (we have servers in<br>
three suites; this is consolidating to two suites soon though).<br>
<br>
Nothing helps with (c) because we&#39;re still single-homed to one<br>
network provider. As far avoiding (c) goes your best bet at the<br>
moment is a different provider in a different datacentre.<br>
<br>
Cheers,<br>

&gt; We&#39;ve been looking at some type of domain/DNS failover. But for us,  I&#39;d<br>
&gt; like the other VPS to be at least in a different part of the city (if not<br>
&gt; country). Also, the site that does the failover management should be in yet<br>
&gt; another location. I suppose IP failover to a different box is of some value<br>
&gt; in the event that a box has problems, but would it help in common scenarios<br>
&gt; such as (a) network routes down or (b) power failure?<br>
