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??
We’ve all.committed that sin before. Its better to rely on it surviving the reboot than to try prevent the reboot.
Also worth looking into some form of uptime monitoring software. When something goes down, you want to know about it asap.
And documenting your setup never hurts :D
On the uptime monitoring I’ve been quite happy with uptime kuma, but… If you put it on the same host that’s down… Well, that’s not going to work :p (I nearly made that mistake)
It’s not the most detailed thing, but I just use a free account on cron-job.org to send a head request every two minutes to a few services that are reachable from the internet (either just their homepage or some ping endpoint in the API) and then used the status page functionality to have a simple second status page on a third party server.
You can do a bit more on their paid tier, but so far I didn’t need that.
On the other hand, you could try if a free tier/cheap small vps on one of the many cloud providers is sufficient for an uptime Kuma installation. Just don’t use the same cloud provider as all other of your services run in.
