This is not aimed at anyone in particular, but i find it amazing how many people host their rig in a datacentre,
apparently so anyway. Is that what we're calling our garage now then? Unless you work somewhere that already has rackspace going spare, a hosted solution in a REAL datacentre would mean that you no longer really make any profit from your rigs, unless you have somehow found an EXTREMELY cheap sub-let option. Plus what kind of datacentre would let a big, exposed thing like our typical miner rig is, sit in a rackspace? Hardly any... you would usually be forced to keep non-rackable hardware in one of the cages/suites, which cost even more. I work in IT, and i've done plenty of installs in datacentres around Europe, so unless it's very different in the US then i'm having a hard time buying most of these claims. I mean, oh really, you have your 750KH 'rig' in a professionally manned datacentre and pay for the rental of the space, for that!? Come on now...
Also, my buddy rented a rig the other day that went offline 10% in to the rental. It said it had "monitoring" also, but it never came back online. I'm starting to doubt a lot of people who claim to have these "pro hosted" services/solutions in place. So buyer beware, look at the feedback more than the fancy words!

And for those people using fancy service names like "monitoring", when they actually mean "
i have a smoke alarm in my house", or something. If any of you want to stop bullsh*tting your customers and actually set up some free and effective monitoring, check out
PRTG Network Monitor. It's free, easy enough to configure (if you can set up a rig, you can do this) and has email alerts, etc. Even if you can't be bothered using all the sensors, a simple 'ping' test once per minute is better than nothing at all.
Do everyone a favour and take ~10 minutes for installed something like this, everyone benefits (especially your feedback)! It's not like i'm asking you to configure Nagios or Zabbix, that would be more cruel.

You are probably right. I have seen "Data Center hosting" together with specs of 5000KVA UPS backups. Not really Data Center if you ask me...
Some, like me, really have our rigs in data centers. How is this possible? How can i profit doing this? Easy answer: I'm not paying for it. How? Well, my company pay for the rack. At this specific location we only utilize a total of 3U. 2U worth of Routers and a single 1U server. We use this location only for routing and the server for monitoring other sites, so we have almost an entire rack empty. Since power is included in the fixed rent all i had to do is convince my boss to let me put my "small" 3-card setup in there. Here is "proof" of my monstrous rig built on to a rack shelf installed:
From what i know most DCs allow their customers to have whatever they want in their racks. Only real regulations i have seen is banning of cardboard boxes and other non electronics being stored in them since it is an obvious fire hazard.
So if you want a rig hosted in a real data center, check mine out.
