The number of people in that thread who stuck metal tools into their PSUs is… shocking
Brilliant thread, love reading these stories.
My favorite story along these lines was about the sales guy who claimed his emails only seem to go about 200 miles before getting rejected. He was actually able to demonstrate this to the surprise of the sysadmin - email to recipient 100 miles away went through but recipient in the next state received a bounceback. This was reproduceable to multiple unrelated destinations.
After some investigation of the mail server config, it turned out the SMTP relay had a very low timeout value for connecting to destination servers, something like 50ms, so any WAN hops that were further than 50ms away (which equated to around 200 miles) would time out before sending SMTP traffic.
Back when I was doing support, I found the most challenging part of it was translating people’s impressions of what is happening to what is actually happening. Often with amusing results.
