After a couple of days of being stuck at work, family issues, and generally not feeling well, I left cbaduk.net alone for a while… and figured out the server simply crashed.
Ugh.
google cloud console says the machine is running, but it is not responding to anything. No ssh, no web, nothing.
Without much choice, I rebooted the machine, opened a terminal, and started to have a look – and the syslog showed that the machine crashed running out of memory.

The whole server was running on a f1-micro instance (the smallest instance on Google Compute) which has a grand total of 0.6GB of DRAM. Running nginx+php+mysql.
*sigh*
My first web server was an Athlon 1.4GHz with 256MB of RAM which I managed to shove it in the computer room back when I was in college. Running Red Hat 9. It was running a couple of webpages, with php and mysql, while running all the code that I needed to run for my term projects… and now 600MB won’t even get me to the point of running an website with near-zero visitors.
(Yeah yeah, I know there are people much older than me that will say that their first server was something with 256MB in hard drives…)
Well, I do appreciate how easy things are now. I launched another server, installed mysql, and then migrated the database from the web server to another separate f1-micro instance. Took around 15 minutes.
If this was year 2001, it probably took me another day to find/buy parts (assuming I have the money to buy something), figure out how to get another IP, assemble all the parts, and then struggle getting the required rpm files.
