Repeated missingblockserror

Hello! I'm currently running bloomz-petals on a Google Colab notebook in order to make use of the free GPU. However, I've recently started receiving the following error:

MissingBlocksError: No servers holding blocks 0 are online. You can check the public swarm's state at
http://health.petals.ml/ If there are not enough servers, please connect your GPU:
https://github.com/bigscience-workshop/petals#connect-your-gpu-and-increase-petals-capacity

The public swarm's state seems okay and I can sometimes get everything to work (it's a dice roll). If anyone could please explain this error and give ideas to solve it, that would be extremely helpful! Thank you!
