URGENT: `What is My ISP?` tool's `ip address lookup` breaking, seeing constant API errors!

• Thorough API Provider Audit: Even if you switched, the new provider might have its own quirks. Verify their status page for outages, review their Service Level Agreement (SLA), and check if their documentation has changed recently. Sometimes, a provider might subtly alter their response format or add new rate limiting tiers without major announcements.
• Request Integrity Check: The 403 errors and malformed JSON often indicate an issue with your request. Double-check your API keys, headers (e.g., `Content-Type`, `User-Agent`, `Authorization`), and the overall request body against the API provider's exact specifications. Even a minor deviation can lead to unexpected responses or outright rejections.
• Network Path Diagnostics: Timeouts suggest potential network issues between your server and the API endpoint. Use tools like `traceroute` or `mtr` from your server to the API provider's domain to identify any latency spikes or packet loss along the route. Your server's outbound firewall or security groups could also be intermittently blocking connections.
• Enhanced Logging: Implement more verbose logging for failed requests. Capture the *full* request (headers and body) sent to the API and the *raw* response received, including all headers, before any parsing attempts. This will help you pinpoint if the malformed JSON is coming from the API itself or if your parsing logic is failing. Remember to redact any sensitive information from logs.
• Rate Limit Granularity: While you checked rate limits, some providers have complex rules that might include burst limits, concurrent request limits, or different limits for specific endpoints. Ensure your implementation accounts for these, perhaps with an exponential backoff strategy for retries.

That "Request Integrity Check" was spot on, turns out one of my headers was kinda wonky, thanks for the save! Now that the core lookup works, I'm seeing weirdly slow responses for certain international IPs, wondering if network path diagnostics is still the next step for that.
