Theft/Security is a huge concern with low-end "data centers". Sometimes they're not even (private/their) datacenters and unless you do research you would never know they're just showing pics of someone elses datacenter and they have a half rack or full rack in it... they don't pay their bill for some reason all their equipment is gone, and by
their I mean yours too.
I've also had issues with low-end data center employees that are not exactly caring about what they do.
IE: Bumping power cords or pulling power cords to "find the right one", re-assigning your IPs to someone else, and other stuff that causes down time and very hard for you to troubleshoot on your end, and you're at the mercy of their employee or who they sub-contract to on-site.
Then you get into the cheap bandwidth, or bandwidth limitations they may have not tell you about but impose on you during
their high demand times, or from their provider due to them overselling, etc...
15-18 years ago I used to hop around data centers as prices were SUPER CHEAP and they were ALL trying to get new customers as it was really new for smaller businesses to need the datacenter services. Over time they either got acquired or went out of business. But 1 thing happened across the board, and that's prices went up up up.
My 02 - you get what you pay for. Just know you're giving up
something for a very low price
Figure out what it is, and if your'e OK with that then go for it. I'd be much more inclined to go with a cheap provider that has a 4hr response time but everything else is 'great' vs one who has a 20m response time but goes down 1hr every couple days due to infrastructure issues.
