I have had the same problem for at least a month!!! Do you guys block certain accounts for some reason?

[ChuaCheowHuan]

Hi, I'm having the same issue with Colab (default settings) on Chrome. I'm not using Colab's GPU or TPU.

[pratikbits]

[abdimk]

am having this problem like for a month

[testonamonaco]

It's happening again! Colab says "Sorry, no backends available. Please try again later."

[rcanand]

Just happened again. But after a couple of refreshes, got through.

[annidamf]

hello, it's happening to me now, is anyone else experiencing it?

[TranHuuNhatHuy]

@annidamf same for me, seems something's broken on Colab's side

[yashrooprai]

Same for me aswell

[annidamf]

I hope they fix it as soon as possible :)

[aditikilledar]

I’m facing the same issue. Using colab’s default settings.

[craigcitro]

For all the commenters in the last 3h: We had an availability issue on our side, which led to failed GPU assignments; we believe we've found the root cause and the issue should resolve shortly.

[olusegunajibola]

Yes, I thought I was the only one.

Hoping the system gets back up ASAP.

[annidamf]

amazing, thank you!! :) @craigcitro and the team

[leduy99]

Hi, I'm also having this though I didn't train much last week :( Please fix :(

[radames]

thanks @craigcitro it would be great to have Google Colab on the Google services status https://status.cloud.google.com/

[aritraMandal02]

Hi, I am getting this issue right now. My colab is not connecting to runtime, Only showing Allocating and after a long time it says 'No backend available. Please try again later.' Tried with different accounts not fixing.

[Onyoursix]

Also getting no back end issue, good to know it isn't just me!

[souvikb1812]

[aritraMandal02]

Thanks. It is working now.

[githubdotcomuser]

I have been getting this error message for the last few days. Is there any solution?

[sergio21w]

I have the same problem but it is due to illegal downloads. I think they ban you.

[DanialPahlavan]

I think to check your running code before executing it. I have this problem and i read rules and there is a section for that. I hope its nor be permanent because we are just tinkering with our code for learning.

file hosting, media serving, or other web service offerings not related to interactive compute with Colab downloading torrents or engaging in peer-to-peer file-sharing using a remote desktop or SSH connecting to remote proxies mining cryptocurrency running denial-of-service attacks password cracking using multiple accounts to work around access or resource usage restrictions creating deepfakes

[DanialPahlavan]

creating deepfakes :)
