I was logged out automatically from GitHub Copilot. Logging in again had no effect. For a few minutes the status page https://www.githubstatus.com/ showed just "Issues" and "API Requests" were down but now even Copilot itself is showing up as degraded.
Same issue, if I look at the copilot logs I see "[info] [auth] Invalid copilot token: missing token: 403". Seems like the issue is on their side though, judging by general website issues.
This is why I'm cautious about tools that become too integrated into daily workflow. When Copilot goes down, entire teams slow to a crawl.
Don't get me wrong - AI coding assistants are incredibly useful. But building dependencies on external services for core development work creates single points of failure.
Always have a backup plan for when your tools inevitably break.
