I woke up this morning to a text from my ISP, “There is an outage in your area, we are working to resolve the issue”
I laugh, this is what I live for! Almost all of my services are self hosted, I’m barely going to notice the difference!
Wrong.
When the internet went out, the power also went out for a few seconds. Four small computers host all of my services. Of those, one shutdown, and three rebooted. Of the three that ugly rebooted some services came back online, some didn’t.
30 minutes later, ISP sends out the text that service is back online.
2 hours later I’m still finding down services on my network.
Moral of the story: A UPS has moved to the top of the shopping list! Any suggestions??
A general tip on buying UPSes: look for second hand ones - people often don’t realise you can just replace the battery in them (or can’t be bothered) so you can get fancier/larger ones very cheap.
Also, a larger capacity one is better, and it’s likely you’ll find a secondhand one with more capacity/features for a similar price.
Why? If the power has gone out there are very few situations (I can’t actually think of any except brownouts or other transient power loss) where it would be useful to power my server for much longer than it takes to shut down safely.
Longer means you’re more likely to be able to ride out a power cut, and gives you more options if you want/need to complete something more involved than saving and shutting down.
