World border

The World Border is a semi-transparent wall that surrounds the Minecraft world. The Border is 30 million blocks from all four sides and is around the center of the world (Spawn, 0, 0). It was made so that players could not venture into glitched chunks. Back in the days, if you went far enough to 12 million blocks, you would reach the Far Lands, glitched terrain that would make mountains that reached the skies, and infinitely long caves. Mobs also acted weird there. And if you went even further, you would fall through the terrain, and shading did not seem to work. However these Far lands where eventually removed.

Overworld
The history of the World Border is clouded in mystery, as it was reached first sometime in 2011 through a backdoor. This is known due to the findings of chunks from 2011 at the -X Axis Highway. This might have been reached through popbob's or Acid1212's (supposed) backdoor. The modern World Border was first reached by pyrobyte and iTristan through their backdoor on December 7th, 2013 on the +X axis. There they left some bedrock and two signs. They also teleported to the -X, and the -Z, world border's but did not leave anything there.

+X: On March 26 2017, the X+ world border was reached by xxq), rasqi, MiningMinecraft, househousehouse1, and Auion. The final stretch of digging was streamed on twitch by xxq and later uploaded to youtube. The base Point Nemo was founded at the world border and lasted less than a week. Point Nemo was griefed by Babbaj. After Point Nemo's grief, the X+ world border area was turned into "new spawn" by Nordic93, who made a giant lavacast wall, similar to his well known ones at spawn. This was the first World Border in Minecraft history to be reached by digging.

After this event. many other groups such as a +Z Diggers, and -X diggers where formed to finish the Highways to the other borders.

-X: The -X Diggers reached the border on December 22nd 2017, and made a giant Christmas tree as they arrived 2 days before Christmas. And later exchanged gifts with each other.

+Z: The +Z Diggers reach the border on June 9th 2017. This was the only OverWorld border that had not been teleported too.

-Z: The -Z border was the only one to be reached by flying first before digging. the player gRiNdLoRd under the Nether floor flew to the border for 10 hours. Reaching it on August 7th, 2017. The Highway was later completed by the group Highland.

End
The End World Border was first reached by Armorsmith when he took a week to fly using packetfly, lagging the server in the journey.

Nether
In March 2020, 0x22, IronException, and l_amp visited all main axis and corner world borders in the Nether, using a teleportation exploit. The Nether world border was first reached via mining, on the +X Highway, by the Motorway Extension Gurus on May 17, 2021. Previous signs by IronException and l_amp were present at the border upon arrival.
