First, like a week ago I started my first iwstack instance at USA for production use. Previously it was just for tests and so. And I had a mysterious shutdown like a week ago. No idea what happened, but I booted my machine manually.Second, my first support ticket (notice the first, so I never required support until now, which is great) was left unanswered after a little bit of conversation. Maybe they just forgot to answer it and got closed automatically or something. Not a big deal since isn’t an important issue to be honest.

Overall, I am happy. The service is really good for the price, and I am looking forward to see new features in their offerings. Mainly, I hope to get the Milan features at Dallas, like true HA, or native IPV6 and so on.

Provider: Prometeus

Plan: iwStack

Price: ~7€ / month

Location: Milan, Italy


  • 2 cores @ 2GHz
  • 1024MB RAM
  • 10GB root disk (included free) + extra 20GB disk
  • 1 IPv4 and /64 IPv6
  • Unmetered incoming traffic & 1TB/month outgoing
  • Free DNS hosting with Rage4

What the instance is doing:

  • Private email server
  • My website (static site generated)
  • 2 small PHP webapps with MySQL
  • IRC bouncer (znc)
  • Squid private proxy

How it is doing the job:

The VPS is doing its job just fine with no issues. Only time when it felt slow was when my webapp was eating all the ram accidentally :D

Uptime is currently rocking at 133 days. This month I installed uptime monitoring service on a Kimsufi box which reports 99.991% availability with downtime of 4 minutes. (Might have been caused by the kimsufi box and its network though ;) )

The latency from my location (Finland) is 49ms which to me is completely acceptable considering my usage.



I’ve needed a ticket to set a reverse DNS entry for my domain. I set my ticket as low priority and it got answered in an hour, which I find good for low priority tickets. As a previous customer of Prometeus I’ve noticed that all the replies are very polite.

Prometeus – rock solid as usual. Uncle is running a great show. Very stable server. Absolute uptime without it costing an arm and a leg. 5/5 would host business critical apps with.
