Shit, GitHub is dead again?

Get up in the morning, a cup of coffee isn't finished. Open GitHub to pull the code."The page cannot be shown"I don't know.

"I'll do it yesterday!"

Refresher, change of browser, reboot of routers... one operation as big as a tiger, and see if GitHub is blocked.

The circle of friends blew up and the wisher cried:

  • "Deadline, GitHub can't open tonight. I'm going to submit it to you?"
  • “The student party's job is to give GitHub a link. What now? Show the teacher 404?"
  • "The Open Source Project is completely paralyzed and I'm not finished with the bug!"

Don't worry, this is your lifeline!

Why is GitHub so old?

In short:DNS pollution, IP blockade, network fluctuations... Encyclopedia's a bunch of problems.

Sometimes it opens, sometimes it goes straight to 404, depending on luck. But...Programmers never eat on luck.It's a hard-core solution right down there!

3. Updated solution 2025 (personally effective)

1 Renumber Hosts files (most stable but somewhat cumbersome)

Apply scene: A temporary emergency, for a brother who doesn't want to play the ladder.

Steps:

  1. Find the fastest IP: Open Station Master Tool DNS Query,Ingithub.comFind the smallest IP on TTL.20.205.243.166I don't know.
  2. Modify Hosts:

    • Windows:C:\Windows\System32\drivers\etc\hosts
    • Mac/Linux:/etc/hosts
    • Add a Line:20.205.243.166 github.com
  3. Refresh DNS:

    • CMD input:ipconfig /flushdns
    • Mac/Linux:sudo dscacheutil -flushcache

StrengthsFree, stable.
DisadvantagesThe IP may fail in a few days, but it has to be searched again.

2 Mirror stations (sluggers)

Apply scene: Just want to see the code, not log in.

Recommended mirror station:

Strengths: Open to use without configuration.
Disadvantages:Don't log in! Don't log in! Watch out for stolen accounts.

3 Science access (end scenario)

Apply scene: To submit code, to collaborate, to access complete functionality.

Recommended tools:

  • Watt Toolkit (formerly Steam++)One key to accelerate GitHub, White friendly.
  • Dev-SidecarSpecialized in GitHub, opening the door.

Strengths: Steady as an old dog, fast up.
Disadvantages: The software needs to be downloaded and some tools may be walled.

4 Browser Plugin (Edge User Benefits)

Apply scene: Just download the code, not complicate it.

  • Edge Plugin: Search for "Github download link custom acceleration" and replace the mirror source after installation.

Strengths: Simple and rough.
Disadvantages: The limited functionality does not solve all the problems of access.

4. What if GitHub is permanently sealed?

Back up! Back up! Back up!

  • Gitee.: Domestic substitution, but strict scrutiny (you know).
  • GitLabSelf-built warehouse, available for company.
  • Local Backup: Periodicgit cloneGo to the hard drive to prevent sudden death.

The programr's law of survival: Never put an egg in a basket!

5. Finally, say something with your heart.

GitHub is not the first and not the last.But what is the spirit of the coder? - Solve it!

  • Student Party: Learn science to go online and don't cry until the deadline.
  • Hit the workers.The company has more backups. Don't let the boss find out you're fishing.
  • Boss Kai.: Consider moving to GitLab, pre-emptive.
