    Yes, but you can't have IP failover anymore. If the load balancer goes down, your website is offline as well... :(

    Did someone get a reply from Hetzner with good news yet? I read all the related Hetzner forums mentioned here (and 2 or 3 linked there), but apart from some "maybe this, maybe that" there is not a single final reply. I mailed to Hetzner myself just today, but it would be good to now from other users.

    I scan the market for dedicated servers a lot, at least once every 6 months. For the last few years I always ended up with Hetzner winning with the unique combination of features, pricing and powerful hardware. Disabling the flexible IP-Routing is a killer-argument to leave the house - but where to go? From all my scanning I did not find a provider nearly as good. Same service with at least double the pricing or vice-versa. Does someone know an alternative?

    Have a recommendation for everyone. Don't know if you have ever checked out http://www.gplhost.com. I worked with these guys over the last few months and are extremely helpful and supportive. Their prices are also resonable and have multitude of solutions from dedicated servers to xen machines. They prefer to work with the debian distro, but also work with CENTOS, UBUNTU, Gentoo and a few others.

    I phoned with Arno Pirner @Hetzner since there was no reply to my question via mail. The answer was simple and clear: custom IP-Routing (shared IP) will be available in the next Datacenter which is planned to be ready April 2009. Most possibly it will then be available only with an additional (paid) option.

    I'm in contact right now with ovh.de, the upper-class servers are definitly able to share IPs (they have 16 or more ips each which call all be shared). Even the smallest "istgenug" (eng: is enough) servers for 25 Euros/month have a failover-IP assigned. It can be shared, managed by their web interface.
    Until now, they did not give a definitive answer if it can be shared via script (heartbeat etc.), Ill test it as soon as I can get two servers from there.

    Their cheap servers sometimes have issues, which would be no problem in a small failover-cluster of 2 isgenug (available with raid 1 also for 36 Euros). The bigger systems seem to be have better overall stability for a still decent price.

    I was thinking that ovh.de gives you a web interface where you can assign the virtual IP to a server manually, which means it's not automatic and therefore useless for HA. So this is not true for their bigger servers?

    The interface is just used for the special "failover-IP", which even the smallest server has - the bigger ones have 2 or 4 failover-IPs. I found some hints, but no clear answer, that the swich can also be done automatically.

    The bigger servers not only have the special failover-IPs, but also an additional 16+ IP-Range assigned, which can be used for clustering.

    ovh itself does not guarantee anything with clustering, because they had ready-to-use clusters themselves and want to bring that service back soon.

    Only option I see so far is testing - I just ordered 2 isgenug. If you're interested in testing for yourself - we could share the month runtime, I just need the servers for one weekend to fully test all functions I need.

    First result: IP-switching is not possible. I have an open ticket on how to remotely control the switch port / routing, no answer yet.

    Second problem was: ovh uses selfmade kernels without module support. There's no "quick install" because the kernel has to be recompiled for a lot of funktionality apart from module support (which is needed for drbd, nfs and other stuff). Positive: the Webinterface is quite nice, you can even partition your drives via webgui for reinstalls.

    Don't they offer distribution images (Debian, Ubuntu, SUSE, etc.) with the distributions' default kernels?

    Nope, just their own kernels (with added support for their special hardware combinations, and missing support for modules).

    They have a broad palette of Linux distributions, even 2 Windows Versions and some ready-to-use virtualization packages (xen, vmware, proxmox), but nothing with the standard kernels.

    And what happens when you install the distribution's standard kernel? Does the system still boot?

    Yes it does work, sometimes a technician has to help, which happens fast and automatically. And if you have special hardware in your box (some have a new Intel Gigabit Ethernet that's not yet in the kernel), there are plenty of patches around the forums. After really intensly testing OVH, I recommend using it, as I myself will do with my first real servers beginning early september.

    Any update on this?
    I know from Feb 2011 added the possibility from Robot to Request separate MAC address for an additional IP.
