There was not a single post about GoGrid, until now.
I am looking for a VPS platform for Virtualmin hosting.
Joe has mentioned Joyent, and a few others, consistently. Joyent looks solid, and I personally like the idea of supporting Sun in some small way by hosting on their gear.
It looks like both GoGrid and Joyent offer a 1 GB machine/"Accelerator" for about $100 a month.
It seems a little odd to me that Joyent doesn't appear to offer a 512 MB VPS, jumping from 256 to 1 GB.
So, for about $100 a month, GoGrid offers a failover setup of two 512 VPS, http://www.gogrid.com/pricing/plans.php with automatic load balancing, which seems better than one 1GB machine, at least theoretically.
And, it looks like their CentOS images have most of the prerequisites that Joe listed, ProcMail, SpamAssassin, and dovecot, leaving only postfix and clam to be added.
However, the support techs seem to have no clue about Virtualmin.
I am interested in some more informed opinions.
