Sudden ping increase playing from South America, anyone else?
This unfortunately won't get you the whole picture, but using some tools you can determine how your traffic is routed in one direction, and possibly the geographic path it takes as well. For example, in mine, I can see based on the names that I know my traffic is going through Equinix San Jose (equinix-sj), then likely to Palo Alto (pao1, palo), then to Los Angeles (lax). By looking up who owns what IP addresses, I can also see that my traffic goes from my local ISP (Sonic) to Telia, then to Amazon. While concerning, you can effectively ignore all of the hops that say "Request timed out." as those just mean the hop wasn't responding to pings (or in the case of the very end, the game server itself likely doesn't respond to pings). Unfortunately though, this is only half of the picture, as this doesn't let me see the path from anets servers to me. For that, I would need an AWS instance with similar routing rules to anet's servers. Still, this may be useful, as I'm guessing your traffic is using a submarine cable to get to anet's servers in the US. These unfortunately often have issues or maintenance that can cause measurable connectivity impacts - I'm in the US and we have a node on the NLNOG Ring, and we get alerts of connectivity issues with Europe on a regular basis.

Zero Point Leet Seconds
Well. Significantly more than that due to latency from switches etc and also because of the fact that there's so little land along the equator, meaning there's only one cable that travels roughly equatorially. It's from Fortaleza, Brazil to Kribi, Cameroon: https://www.submarinecablemap.com/
If you set up a bunch of good first-surface mirrors, I'm pretty sure you could get to pretty much the speed of light. You'd have to put them pretty high up in the air to avoid hitting things (a problem for cables as well, obviously) but putting the beam 2km in the air would still only lengthen the path by 4pi km, or .03%.
I have always found it very neat that the propagation speed of a light wave in glass is roughly the same as electrical waves in a coaxial cable. Both are shockingly slow compared to air/vacuum, but for completely different reasons. In both cases the advantages in signal integrity are immense.

[2023 Day 2] [Python] Stuck on the first task
If you are going to use RE's, use something like https://regexr.com/ to double check that they're doing what you want. I was suspicious of your 'cols = re.findall(r'\d+ .....', i)' line, and indeed it does miss some columns. You should rethink your column detection, and either not use REs or learn how to use capture groups and \w. There would then be no reason to use yet another RE in your column iterator to extract the numbers which you've already detected.

2023 Day 2 Part A [Java] regex pattern not matching
First time posting here, let me know if I need to edit post to conform to any rules. My issue is that I'm trying to match regex pattern to separate out the number of cubes drawn and its color but my Matcher object seems to not be returning any matches so it's throwing a no match found exception when I try to call digitMatcher.group(). I have tested my regex pattern on sites like regexr and it seems to pass there but it's not working for some reason here. I use the same type of regex on day one and it work there so I'm not sure where my regex pattern is failing here. I'm talking about specifically in my isGameValid() method where I create a matcher base on a pattern I made above. Through debugging I know that I separated the string color pairing correctly and that my Matcher object has the correct regex pattern, it's just not matching for some reason. Any help would be appreciated. Code below:
