          Oh man. One of my old companies, the Devs would always blame the network. Even after we spent a year upgrading and removing all SPOFs. They’d blame the network……

          “Your application is somehow producing 2 billion packets per second and your SQL queries are returning 5GB of data”…. “See! The network is too slow and it has problems”

            They might be referring to their brain network being to slow and having problems.

        I always view the source of websites like this and this is one of the worst I’ve seen. 217 lines of code (including inline Javascript?!) and a Google tag for some reason, all to put the word YES in green on black.

          Agreed, could be static HTML and a GIF.

          this made me mad so i made a single, ultra minimal html page in 5 minutes that you can just paste in your url box

          data:text/html;base64,PCFkb2N0eXBlaHRtbD48Ym9keSBzdHlsZT10ZXh0LWFsaWduOmNlbnRlcjtmb250LWZhbWlseTpzYW5zLXNlcmlmO2JhY2tncm91bmQ6IzAwMDtjb2xvcjojMmYyPjxoMT5JcyBpdCBETlM/PC9oMT48cCBzdHlsZT1mb250LXNpemU6MTJyZW0+WWVz
          

          source code:

          <!doctypehtml><body style=text-align:center;font-family:sans-serif;background:#000;color:#2f2><h1>Is it DNS?</h1><p style=font-size:12rem>Yes

            Your website no longer uses DNS invalidating its use as a diagnostic tool lmao

          Did not think of doing that.
