At 09:26 this morning, FUMBBL went down unexpectedly due to a failure of the UPS (Uninterruptible Power Supply, a device that conditions power to the servers and allows the servers to run for a while if there is a power loss).

It took until roughly 12:15 for me to identify the problem, see if there was an easy solution and bypass the broken device, and we are up and running again.

However, I will need to replace the UPS with a new one at some point soon. I will need to do some research on what device I'm buying. If anyone in the community has experience with UPS:es, I'd happily take suggestions on which model to buy.

I have a couple of constraints on what I'm after:
- I'm looking at a budget of $500 to $1000 or so.
- Reputable brand (I've used APC for a very long time, and am happy with the ability to buy replacement batteries etc)
- Preferrably rack mounted (up to 4U), but will consider standalone devices too.
- The hardware runs typically at 550W or so total, and my other UPS was 1000VA which has been fine. There's not a lot of headroom here though, so I am looking for something along the lines of 1000-1500 VA.
- "Smart" functionality (ie, computer communication) is preferrable, but not required.
- Global availability (more specifically I need to be able to order it from Sweden without having to pay insane shipping costs), and needs to be in stock.

Again, if you have experience with these types of devices, I'd appreciate suggestions.

Either way, I apologize for the inconvenience for those of you whose matches this affected. I hope to have this UPS replaced within a couple of weeks (which will unfortunately cause another maintenance downtime).

Edit: The UPS has now been replaced and things should be back to normal again. Thank you kindly to those of you who donated to offset the cost of the replacement.
