The company hosting my virtual server has recently suffered from big problems on their ISCSI infrastructure, leading to major downtimes, affecting all the services I run (mail, web etc.).

Things seem to have been fixed for now. Hopefully, this will never happen again. Just in case, I stopped my order to upgrade the VPS to a more powerful offer (1GB RAM and more proc cycles). I am aware of several hosting companies with cheap and reliable offers (Linode was already cited several times), but most of them are based in the US – Gandi and OVH seem to be the unique affordable alternatives with data center based in France, Gandi being a bit more expensive.

All my apologies for these issues.
