BREAKING: GitHub SSH Deploy Key Connections Failing – Workarounds Inside

GitHub is investigating SSH connection failures affecting deploy keys. Immediate workarounds and status checks available.

GitHub SSH Deploy Key Outage – Live Updates

What's Down

GitHub is currently investigating failures with SSH connections using deploy keys. This impacts:

CI/CD pipelines relying on SSH deploy keys for automated git operations

Automated deployments that clone or push to repositories via SSH

Bot accounts using SSH keys for repository access

Server-to-server git operations authenticated with deploy keys

HTTPS and personal SSH keys may work normally; the issue is specifically scoped to deploy key authentication over SSH.

Immediate Workarounds

1. Switch to HTTPS (Fastest)

Temporarily migrate affected operations to HTTPS authentication: ```bash

Update your git remote

git remote set-url origin https://github.com/user/repo.git

Use GitHub Personal Access Token (PAT) as password

Create PAT with repo scope at github.com/settings/tokens

```

2. Use Personal SSH Keys (If Applicable)

If your workflow allows, temporarily use personal SSH keys instead of deploy keys: ```bash

Test personal key connectivity

ssh -T git@github.com ```

3. Implement Retry Logic

Add exponential backoff to CI/CD pipelines: ```yaml

Example GitHub Actions

name: Clone with retries

run: | for i in {1..5}; do git clone git@github.com:user/repo.git && break sleep $((2 ** $i)) done ```

4. GitHub Token Authentication (HTTPS)

For CI/CD systems, use GITHUB_TOKEN environment variable with HTTPS instead of SSH.

How to Check If You're Affected

Test Deploy Key Connectivity

```bash

This will indicate if deploy key SSH is working

ssh -i /path/to/deploy/key -T git@github.com

Expected working response:

Hi repo-name! You've successfully authenticated...

```

Check CI/CD Logs

Look for these error messages:

Permission denied (publickey)

Could not read from remote repository

fatal: Authentication failed for

Connection timeout on port 22

Verify Your Setup

Visit [GitHub Status Page](https://www.githubstatus.com) for official updates

Check if HTTPS cloning works (rules out general GitHub outage)

Confirm SSH key permissions: chmod 600 deploy_key

Alternatives While Investigating

| Method | Speed | Security | Setup Time | |--------|-------|----------|------------| | HTTPS + PAT | Fast | Good | 5 min | | Personal SSH | Instant | Medium | 2 min | | GitHub App Token | Fast | Best | 15 min | | Webhook retries | Variable | Good | 10 min |

Recommended Short-Term Action

1. Immediately switch to HTTPS + GitHub Personal Access Tokens for critical deployments 2. Monitor GitHub Status for resolution updates 3. Set deployment retries to automatically fallback when SSH fails 4. Document which systems are affected for post-incident review

Recovery Steps (After Resolution)

Once GitHub resolves the issue: 1. Test deploy key connectivity before reverting changes 2. Migrate back to SSH gradually across environments 3. Review and strengthen deploy key rotation policies
