I've used Hetzner for years as one of the places I run jailhosts. Their physical servers are cheap and stable and their support is great especially when considering the price.
I usually use a server for around two years before I start considering retiring it and switcing to a new one. Then it takes me another 1-2 years to actually do something about it. This particular servers was running an old 10.3-STABLE which is EOL long ago, so it was high time to kill it off.
Usually the process is:
Today I retired an old PX70 model server which has been waiting for me to move the last few jails off of it for months. The server was close to 1000 days uptime when I finally shut it down!
10:55AM up 961 days, 15:29, 6 users, load averages: 0.00, 0.06, 0.07
Nothing important (or even public-facing) was running on it for the final 18 months or so, but it did still run some of my monitoring and stuff.
I've had this server for around 4 years, but the disk drives are a bit more than 5 years according to the disk drives S.M.A.R.T. info:
9 Power_On_Hours 0x0012 094 094 000 Old_age Always - 47321 9 Power_On_Hours 0x0012 094 094 000 Old_age Always - 47319
Which comes down to 1924 days or 5.4 years. That is decent. They are both
HGST HUS724040ALA640 4TB drives.
I wanted to share how I wiped the server before returning it to Hetzner.
