Let's Encrypt has halted issuing certificates due "to a potential incident".

My PBS (proxmox backup server) sync fails to my offsite backup because it is over sshfs and doesn't reconnect if either side's internet flaps[0]. I thought this week I should get notifications to @healthchecks_io@fosstodon.org so I would know when it goes down to fix it. Test emails from PBS to myself weren't showing up, figured out I have notifications sending to my self, but I filtered them to a different folder a long time ago. 🤦‍♂️

I knew this was a problem, setup the notification for it, but ignored it because of too much noise.

[0] I should really just run a cron that re-mounts either when it is missing after 5 minutes....I'm sure that won't cause more problems.

Two more copy.fail style exploits have been dropped. I hope everybody enjoys patching and rebooting.

If you are running #unifi you need to patch.

For once the red x is in the middle and not my fault.

The amount of people paged and working on the #youtube outage is likely equal to a large town.

The TLA of the Internet apocalypse. DNS, BGP, AWS.

What is your preferred ntp client for your Linux systems?

I've let the magic smoke out of usb c cable.

It was one that showed how much power was flowing through it, so.... Glad I caught it and it didn't start a fire.

Happy #newyear!

How many ! are too many? Upgrading a Dell switch.

Do you keep your passwords and 2FA in different applications?

I'm impressed with @cira@mstdn.ca DNS shield.

I saw a post on r/rogers asking if a text message was a scam. I took the domain and check it against Hagezi's TIF, nope, Quad9? Nope. CIRA DNS? Detected!

Maybe CIRA has a better Canadian scam feed.

If only the Internet is down at your house, how many alerts do you get?
