Dropped $180 on a refurbished Juniper switch off eBay and it died after 3 weeks.

No warranty, no return, just a brick and a lesson that buying used enterprise gear from a random seller is basically gambling has anyone else gotten burned on refurbed Cisco or Juniper stuff?

Met a guy at a coffee shop who changed how I think about subnets

So I was sitting at this local coffee shop in Austin last month, waiting for my latte, and this older dude notices my laptop has a network diagram on screen. He asks what I'm working on, and I tell him I'm trying to figure out why our office VLANs keep overlapping. He just laughs and says 'stop thinking of subnets as walls, think of them as doors instead.' That totally clicked for me. He went on to explain how he sets up his commercial networks with a /23 for flexibility but uses ACLs to control traffic instead of strict subnet boundaries. It's been a month since I tried his approach on a small office build and it's working way smoother. Has anyone else run into an old school trick like that that just made everything simpler?

TIL our office building has a hidden fiber junction box in the ceiling

Was tracing a network dropout last week and popped a ceiling tile in the break room. Found an old fiber junction box from 2008 nobody knew about, still patched into the main closet. Has anyone else stumbled into abandoned infrastructure like this?
