The straight answer#
A Claude Code outage is an upstream service failure only when requests fail across repositories, sessions, and machines while local execution still works. One broken prompt, tool call, login, hook, or repository does not prove an outage. Treat “Claude Code is down” as a diagnosis to establish, not a convenient label for every failure.
Claude Code is an agentic coding tool that can inspect a codebase, edit files, run commands, and work through development tasks. That makes its failure surface much larger than a normal chat interface.
The practical distinction is simple:
| Observation | Most likely category | |---|---| | Requests fail in unrelated repositories and fresh sessions | Upstream service or account-path problem | | Only one repository fails | Repository context, instructions, hooks, or command problem | | Claude responds but a command fails | Local toolchain or environment problem | | Authentication fails everywhere | Credentials, account access, network, or upstream authentication | | One long session behaves badly | Session state or accumulated context | | Teammates can work but you cannot | Local environment, network, configuration, or account |
Do not keep retrying destructive or stateful operations while the failure category is unclear. An agent can stop after partially editing files, running only part of a command sequence, or producing a response that no longer matches repository state. “The request failed” does not mean “nothing changed.”
The correct immediate move is to preserve the repository, classify the failure, and decide whether the work can continue safely without the agent. That discipline matters more than proving who owns the incident.

The evidence#
The strongest evidence of a Claude Code outage is failure that survives controlled changes to local variables. If a minimal request fails in a fresh session, outside the affected repository, and on another known-good environment, the case for an upstream problem becomes strong. A single complex task provides weak evidence because it exercises too many components.
Claude Code is designed to interact with files, commands, development tools, and project context, as described in the official Claude Code documentation. Each interaction introduces a boundary where failure can occur without the core service being unavailable.
Use this isolation sequence:
- Stop the current operation. Record the last confirmed repository state and the exact failure message.
- Check the working tree. Determine whether files changed, commands ran, or generated artifacts appeared.
- Start a fresh session. Ask for a minimal, read-only action that does not depend on the current conversation.
- Move outside the repository. Repeat a minimal request where project instructions, hooks, and repository size cannot interfere.
- Change one boundary. Try another network, machine, or authenticated environment if one is already available.
- Compare with a teammate. Ask them to run the same minimal request, not your original repository-specific task.
The important word is minimal. “Implement this migration and update every caller” is not a health check. “Respond without editing files” or “inspect this small file and summarize it” removes execution, permissions, hooks, and multi-step state from the path.
Failure scope is evidence:
- One command fails: inspect that command and its environment.
- One tool permission fails: inspect permissions and configuration.
- One repository fails: inspect repository instructions and automation.
- Every minimal request fails for one person: inspect network, authentication, and account scope.
- The same minimal request fails for multiple people: escalate as a probable upstream incident.
The official overview explains Claude Code’s broad operating surface. That surface is exactly why a disciplined isolation test beats guessing from a spinner, timeout, or generic error.
The caveats#
The diagnosis changes when failures are selective, stateful, or tied to local execution. Claude Code can remain reachable while a specific capability is unusable. Calling that a full outage is inaccurate, but dismissing it as “just local” can also be wrong when the affected boundary is authentication, permissions, or a shared team configuration.
Three caveats matter most.
First, a partial failure can look random. Read-only reasoning may work while edits, commands, or another tool path fails. Test the capability you actually need, but begin with a read-only request so diagnosis does not create more repository state.
Second, long sessions are poor health probes. Accumulated context and earlier assumptions can make a session fail in ways a fresh session does not. If a new minimal session succeeds, the service is available enough to answer; that does not prove the original task is safe to resume unchanged.
Third, shared configuration creates correlated failures. If an entire team uses the same repository instructions, hooks, network route, or credential setup, multiple people can fail without a global Claude Code outage. The Claude Code documentation describes the tool’s configuration and workflow surface; shared local dependencies must be isolated before blaming the service.
A useful rule is: change one boundary at a time. If you simultaneously switch machines, networks, repositories, sessions, and credentials, success tells you almost nothing about the original failure.

What to do about it#
Protect repository invariants first, then choose the smallest safe continuation path. Do not ask the agent to “try again” until you know whether the previous attempt changed files or executed commands. Recovery begins from verified state, not from the last sentence Claude produced.
Use this incident playbook:
- Freeze agent-driven writes. Pause edits, commands, commits, and deployment actions.
- Inspect repository state. Review changed files, staged changes, untracked artifacts, and relevant command output.
- Re-establish invariants. Run the repository’s normal checks only when they are understood and safe.
- Save evidence. Keep the exact error, operation, and failure scope for team communication.
- Run the minimal isolation sequence. Separate service reachability from repository-specific execution.
- Continue manually when safe. An agent outage should not become a repository outage.
- Resume with a new plan. Give the recovered session the current state; do not assume it knows which earlier steps completed.
Rollback should be surgical. Revert only changes attributable to the interrupted operation, and inspect them before removal. Broadly discarding the working tree is the wrong response in a real repository because unrelated human work may be present.
For teams adopting AI coding agents, outage handling belongs in the workflow before rollout. Define who verifies partial changes, which operations require explicit checkpoints, and what counts as a safe retry. PairFoundry’s foundations provide the starting point for building that operating discipline, while the packs overview groups the available implementation paths.
The larger principle is straightforward: the agent is an unreliable collaborator operating inside a reliable engineering process. If the process only works while Claude Code is available and perfectly stateful, the process is broken.

Related questions people actually ask#
How can I tell whether Claude Code is down or my repository is the problem?#
Run a minimal, read-only request in a fresh session outside the repository. If that succeeds, Claude Code is reachable and the repository, session, configuration, or execution path deserves inspection. If it fails across unrelated environments and users, an upstream or shared infrastructure problem becomes the stronger diagnosis.
Do not use the original task as the test. Repository instructions, hooks, permissions, file volume, and local commands all contaminate the result. The official overview shows why Claude Code’s repository interaction model creates more failure boundaries than a plain chat request.
Is it safe to retry after a timeout or interrupted response?#
A retry is safe only after you inspect what already happened. Claude Code may have edited files or started commands before the visible failure. Repeating the same instruction without checking state can duplicate changes, rerun migrations, or apply a plan against assumptions that are no longer true.
Start from the working tree and command history, not the conversation transcript. Then restate the current repository state and request only the remaining work. For stateful operations, prefer explicit checkpoints over one large instruction.
What should a team standardize before relying on Claude Code?#
Standardize checkpoints, ownership, and recovery—not prompt wording alone. Every team should know when agent writes must pause, how partial changes are reviewed, which commands need human confirmation, and how work continues when the service is unavailable. Those controls keep repository correctness independent of agent availability.
The official Claude Code documentation explains product operation, but teams still need their own rules for invariants, review boundaries, credentials, shared configuration, and rollback. Official product guidance is not a substitute for repository governance.
When should we avoid using Claude Code during recovery?#
Avoid it when repository state is unknown, the failed operation may have external side effects, or safe rollback requires human judgment. Recovery is the wrong moment to grant an uncertain agent another broad instruction. First establish what changed, what completed, and which invariants still hold.
Use Claude Code again only when the next action is bounded and independently verifiable. If a manual fix is faster and safer, take it. Agent availability is useful; agent dependency is an architectural mistake.
