# High Priority Tasks - Progress Report

**Date**: 2026-01-05  
**Status**: In Progress

---

## Task Status Overview

### ✅ Completed Tasks

1. **Cloudflare Tunnel Investigation**
   - ✅ Reviewed Cloudflare dashboard requirements
   - ✅ Checked tunnel connection pool settings
   - ✅ Checked Cloudflare edge caching issues
   - ✅ Identified root causes (timeout errors, QUIC stream failures)
   - ✅ Documented findings in `CLOUDFLARE_TUNNEL_INVESTIGATION.md`

2. **Client-Side Retry Logic Design**
   - ✅ Designed exponential backoff strategy
   - ✅ Created example implementation (`scripts/rpc-client-retry-example.js`)
   - ✅ Implemented retry for 502/503/504 errors
   - ✅ Added jitter to prevent thundering herd

### ⚠️ In Progress Tasks

1. **Client-Side Retry Logic Implementation**
   - ⚠️ Example code created
   - ⚠️ Need to integrate into client applications
   - ⚠️ Need to test with real requests

2. **Cloudflare Tunnel Configuration**
   - ⚠️ Need to update cloudflared service with keep-alive settings
   - ⚠️ Need to configure connection pool
   - ⚠️ Need to review Cloudflare dashboard (manual step)

### 📋 Pending Tasks

1. **Monitoring/Alerting Setup**
   - Set up alert when 502 rate exceeds 30%
   - Configure monitoring for success rate trends
   - Set up tracking for response time patterns
   - Configure alerts for service downtime
   - Set up monitoring for Cloudflare tunnel health
   - Track error rates by endpoint and RPC method
   - Monitor system resource usage with alerts
   - Set up alerts for Besu sync issues

2. **Web3Signer Configuration**
   - Import signing keys to Web3Signer service
   - Configure Web3Signer key management policies
   - Test transaction signing via RPC Translator
   - Verify Web3Signer keys are properly secured
   - Document Web3Signer key rotation procedures
   - Set up Web3Signer key backup procedures

## Key Findings

### Cloudflare Tunnel Issues
- **Root Cause**: Network activity timeouts and QUIC stream failures
- **Impact**: 40-60% failure rate on public endpoint
- **Solution**: Configure keep-alive, increase connection pool, implement client retry

### Client Retry Logic
- **Status**: Example implementation complete
- **Features**: Exponential backoff, jitter, configurable retries
- **Next**: Integrate into client applications

## Next Actions

1. **Immediate** (Today):
   - Update cloudflared service configuration
   - Test retry logic example
   - Check Web3Signer service status

2. **Short-term** (This Week):
   - Integrate retry logic into client applications
   - Set up basic monitoring/alerting
   - Configure Web3Signer keys

3. **Medium-term** (This Month):
   - Complete monitoring setup
   - Optimize tunnel configuration
   - Document all procedures
