All model encounter high traffic, IDE totally not usable, chain breaks in second

This has been a long time trend but this morning, usually change models fix it. This morning all models encounter high traffic. Even continue a few times get into the generating step, chain breaks very soon due to high traffic error. IDE is not usable for this moment. Tried uninstall and install, updates, disable mcp and delete skills and rules, no help. All calls were strictly contained in IDE, no violation.

Ultra plan, base in US, no quota has been used since it is always high traffic.
