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??

    My favorite part about using an old laptop as a 24/7/365 plugged-in server is the anticipation of when the lithium battery will explode from overcharging.

      “overcharging” doesn’t exist. There are two circuits preventing the battery from being charged beyond 100%: the usual battery controller, and normally another protection circuit in the battery cell. Sitting at 100% and being warm all the time is enough for a significant hit on the cell’s longetivity though. An easy measure that is possible on many laptops (like thinkpads) is to set a threshold where to stop charging at. Ideal for longetivity is around 60%. Also ensure good cooling.

      Sorry for being pedantic, but as an electricial engineer it annoys me that there’s more wrong information about li-po/-ion batteries, chargers and even usb wall warts and usb power delivery than there’s correct information.

        Isn’t dendrite formation and the shorts they can cause a much bigger concern when dealing with old batteries that are being charged 24/7? Asking a genuine question here, so please don’t shoot me if I’m wrong. 🙂 I’d love to hear more about the most common failure modes and causes for li-po/ion batteries.
