Description:

Since yesterday, I have been unable to use Colab notebooks. After waiting for over 8 hours yesterday and 1.5 hours today, the system fails to establish a stable connection to a backend.

Steps to Reproduce:

Open any notebook (including a blank one).

Click "Connect" or attempt to run a cell.

Observe the status bar remaining in "Connecting," "Allocating," or "Initializing" indefinitely.

Technical Details to Include:

Account Type: (Free / Colab Pro / Colab Pro+)

Runtime Type: (Standard / GPU / TPU)

Browser: (e.g., Chrome v144, Firefox, etc.)

Region: (Your general location, as this can be a regional server issue)

What I've Already Tried:

Clearing browser cache and cookies.

Incognito mode (to rule out extensions).

Switching from GPU to CPU runtime.

Using a different internet connection/VPN.
