How to Fix Claude Degraded Performance Error

What does degraded performance mean for Claude?

"Degraded performance" is a status flag indicating that while Anthropic's servers are technically online, they are operating under heavy stress or experiencing microservice failures. For users, this translates to extremely slow generation speeds, messages that stall mid-sentence, frequent "connection lost" banners, or temporary UI glitches in the claude.ai web interface.

When Anthropic declares degraded performance on their status page, their internal queues are overloaded, and priority queuing rules are applied to manage the load. This article provides actionable steps to optimize your client-side environment and bypass bottlenecks during these high-latency periods.

How to troubleshoot Claude degraded performance

When the system experiences high latency or intermittent failures, you can mitigate the impact by adjusting how you interact with the service.

1. Monitor the official incident logs Your first step should always be to confirm if the sluggishness is a global system event. * Navigate to `status.anthropic.com`. * Look for the **API** and **Claude.ai (Web Application)** components. * Check the historical incident logs at the bottom of the page to see if engineers are actively deploying a fix or performing database maintenance. If they are, expect elevated response times until the incident is resolved.

2. Downgrade to a lightweight model During periods of degraded performance, high-tier models like Claude 3.5 Sonnet or Claude 3 Opus experience the highest queue densities because of their compute-heavy processing requirements. * **On the Web App:** If you have access to multiple model options, switch to a faster, less resource-intensive model if available. * **On the API:** Dynamically route your traffic to a lighter model like Claude 3 Haiku (`claude-3-haiku-20240307`). Haiku has significantly lower latency and requires fewer computing resources, making it much more resilient during platform-wide congestion.

3. Disable browser extensions and network shields During degraded performance events, Claude's WebSockets connection (which handles live message streaming) becomes highly sensitive to latency. Security and ad-blocking extensions can disrupt these fragile connections. * Open an incognito or private browsing window with all extensions disabled. * Log in to `claude.ai` and test a prompt. * If performance improves, temporarily disable extensions that inspect network traffic, such as ad blockers, script blockers, or third-party antivirus web protection tools.

4. Implement exponential backoff in code (For Developers) If you are running automated systems via the API during a degraded performance window, unhandled failures will disrupt your workflow. You must implement robust retry logic with exponential backoff to handle rate limits and server struggles. * Do not immediately retry failed requests in a loop; this exacerbates server degradation. * Implement a backoff algorithm that waits progressively longer between retry attempts, introducing a random "jitter" to prevent synchronized retry spikes. ```python import time import random from anthropic import Anthropic, APIConnectionError, InternalServerError

client = Anthropic()

def safe_completion(prompt, attempt=1): try: return client.messages.create( model="claude-3-5-sonnet-20241022", max_tokens=500, messages=[{"role": "user", "content": prompt}] ) except (APIConnectionError, InternalServerError) as e: if attempt > 5: raise e # Exponential backoff with jitter sleep_time = (2 ** attempt) + random.uniform(0, 1) time.sleep(sleep_time) return safe_completion(prompt, attempt + 1) `

5. Clear active service workers Corrupted browser service workers can continue attempting to reload broken WebSocket channels even after Anthropic's servers have recovered. * In your browser, open Developer Tools (`F12` or `Ctrl + Shift + I`). * Go to the **Application** (or **Storage**) tab. * Click on **Service Workers** in the left menu. * Find the service worker associated with `claude.ai` and click **Unregister**. * Reload the page to force a fresh connection registration.

When to escalate

If the status page declares all systems "Operational" but you continue to experience severe performance degradation (e.g., responses taking longer than 60 seconds or failing to start streaming entirely) across different networks, contact support.

Before submitting a ticket, run a traceroute to api.anthropic.com or claude.ai from your terminal and save the output. Include your physical location and ISP name in your support ticket to help engineers isolate regional ISP routing degradation.
