thank god the site is back up again, that outage was scary. on a more relevant note, yay, another long data page! - '''[[User:Vaedez|Vaedez]]''' ([[User talk:Vaedez|talk]]) 02:43, 2 July 2026 (UTC)
:Must have missed that (can see other references to it below). It was working before I went to bed (this wasn't here yet), but I'm guessing it's the same overzealous webscraping/watever (automated, either by hand or AI 'material grabber') that we had over a few days last month. Though must have started later and finished far earlier, this last session. [[Special:Contributions/82.132.236.125|82.132.236.125]] 13:06, 2 July 2026 (UTC)

: yeah, that'll be due to an issue with the site/the bot that generally creates the comic pages (as mentioned in "created by a BOT") having trouble uploading to the site - '''[[User:Vaedez|Vaedez]]''' ([[User talk:Vaedez|talk]]) 04:39, 2 July 2026 (UTC)
: okay, i think i uploaded the image correctly? its certainly in now, and i didn't touch how the image is embedded, but it looks maybe too big in the page - '''[[User:Vaedez|Vaedez]]''' ([[User talk:Vaedez|talk]]) 04:46, 2 July 2026 (UTC)

I'm a bit surprised that the Deepwater Horizon Bore Hole didn't get an "Oops" tag. [[Special:Contributions/60.240.65.62|60.240.65.62]]

The russian hole got filled in again, they we're afraid of deamons. The deepest hole that ist still open is KTB in Windischeschenbach at 9101m [schobi]

Did nobody notice that Randal made a typo in the word bochnia? [[Special:Contributions/217.95.141.233|217.95.141.233]] 05:18, 2 July 2026 (UTC)

Point the first: Surprised that CERN didn't get a look in. Not ''particularly'' deep, but then again some of the others aren't, and maybe even are also "far wider than deep". And CERN's 'underground ring(s)' hole is very much in Randall's awareness. Makes you wonder what other examples were deliberately left out. [[Special:Contributions/82.132.236.125|82.132.236.125]] 13:06, 2 July 2026 (UTC)

Point the second: I think there needs to be two 'depth' columns in the table. The one currently there is (I think) all "(height above/)depth below MSL", but a second column for "maximum depth below the local surface" (or better description) might be useful. i.e. the mountaintops they're dug in below (even if tunnelled in from the side, it's the 'overhead' rock, not the 'shaft-depth', though notes about that might not go amiss). For the Dead Sea it ''is'' at its own surface (though its depths are at watery depths starting from that below-sealevel point). The oceanic ones would be depth below the (surrounding?) sea-floor. - I can trivially add in the whole column, right now (and set it up for proper useful datasortvalue, etc), but would have to leave it blank of data until I can actually do enough of the research. Rather than that, just mentioning it. Maybe someone else has the time, before I do (this evening, maybe?). [[Special:Contributions/82.132.236.125|82.132.236.125]] 13:06, 2 July 2026 (UTC)

According to Wikipedia the Ryfylke Tunnel is not ONE of the deepest subsea road tunnels but THE deepest tunnel of any kind. It is expected to be surpassed by a tunnel planned to be completed in 2033 (also in Norway) 13:33, 2 July 2026 (UTC)

Diggy diggy hole! [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 14:08, 2 July 2026 (UTC)
: Not including the Mines of Moria seems like a significant oversight on Randall's part. [[Special:Contributions/82.13.184.33|82.13.184.33]] 14:25, 2 July 2026 (UTC)

Maybe it's worth separating elevation column into elevation on surface and elevation of deepest point? Or maybe add "depth"?
