The platform also emphasizes the importance of managing AS-SET memberships for an ASN to ensure routing integrity. These tools and analyses are essential for network operators to maintain security and performance within the complex ecosystem of global internet routing and to prevent potential traffic redirection or outages caused by configuration errors.

Users can now subscribe to GitHub status updates via email or SMS. Email notifications cover incident updates, while SMS notifications are specifically for the creation and resolution of incidents. A phone number verification process is required to enable text message alerts, while email subscription can be activated immediately.

GitHub resolved an incident involving degraded performance and elevated error rates across multiple services, including Actions, Issues, Pull Requests, Webhooks, and Codespaces. Systems are recovering, and a full root cause analysis will be shared soon.

The GitHub Status page tracks service uptime and reliability, currently showcasing a record-breaking streak of consecutive days without incidents for 2026. This metric highlights the platform's commitment to stable infrastructure and operational excellence for developers relying on GitHub for critical workflows and version control.

Site Spy is an automated website monitoring tool that tracks content changes with visual diffs and element-specific snapshots. It features cross-device synchronization, a web dashboard, and integration with AI agents like Claude via the Model Context Protocol (MCP), allowing users to receive instant notifications and summaries of updates.

Users can subscribe to real-time status updates for Claude.ai and its API via email or SMS. By providing contact details and verifying mobile numbers, subscribers receive notifications regarding service interruptions, incident updates, and resolution statuses globally.

GitHub experienced service degradation on April 20-21, 2026, affecting code scanning, code quality analyses, and project boards due to a serialization error. The issue prevented triggers for pull requests and updates on project boards. GitHub mitigated the incident by deploying fixes, updating event consumers, and reindexing project items, while planning improved monitoring and schema validations.

Fluid is a specialized infrastructure automation tool designed to streamline development workflows through high-fidelity sandbox isolation. By allowing users to instantly clone VMs, Fluid provides a safe environment to test changes in isolation before they ever reach production. The system is context-aware, meaning it explores the host environment including the OS, installed packages, and CLI tools to adapt its behavior accordingly. Security and accountability are central features, offering a full audit trail where every command and change is logged for review. Furthermore, Fluid enhances reproducibility by auto-generating Ansible Playbooks based on the activities performed within the sandbox, bridging the gap between experimentation and production-ready infrastructure code.

A service outage affecting GitHub Actions, Copilot, and Webhooks has been successfully resolved. Engineers identified the root cause and implemented mitigation steps to restore full system stability. A detailed analysis of the incident will be provided in a follow-up report.

Users can subscribe to real-time incident updates for Pull Requests, Issues, and Git Operations via email or SMS. Email notifications provide status updates, while SMS alerts cover incident creation and resolution. To receive text messages, users must verify their phone number via a one-time password (OTP).

NetViews is a professional-grade network diagnostic and monitoring application designed specifically for macOS. The tool provides real-time dashboards that offer immediate visibility into every connection, allowing users to discover all devices on a network and track their uptime with custom alerts. Key features include Wi-Fi signal analysis, channel congestion monitoring, and noise level tracking to optimize wireless performance. Additionally, it offers deep-dive tools such as ping notifications, DHCP and DNS monitoring, VLAN tag analysis, and Cloudflare-powered speed tests. The software is available in Standard and Pro editions, following a 'buy once, own it' licensing model, with the Pro version offering extended history, timeline views, and advanced Wi-Fi audits to ensure comprehensive network optimization.

Anthropic is currently experiencing system disruptions affecting Claude.ai, the Claude API, and Claude Code, leading to elevated error rates. The team has identified the issues and is actively implementing fixes across these platforms. Users should monitor the official status page for further updates on service restoration.

Users can subscribe to status updates for Elevated error rate incidents across multiple models. Notifications are available via email for all updates, while SMS alerts are limited to incident creation and resolution. To receive text messages, users must verify their phone number; otherwise, opting for email-only notifications remains an alternative.

Sherlock is an open-source transparent proxy tool designed for tech professionals and developers to monitor and inspect LLM API traffic. Built on top of mitmproxy, it intercepts HTTPS traffic to providers like Anthropic, displaying real-time token usage and context window consumption within a terminal dashboard. The tool provides crucial observability for AI developers, including prompt debugging by automatically saving requests as Markdown and JSON files.
