Application stuck in traffic migration

[Nick Clarey]

Hi all,

I thought I'd try using traffic migration to shift versions of my appengine application, but it seems to now be jammed in the migrating state. I thought I'd leave it for a while but at 16 days and counting I'm thinking something fishy is going on.

Is there some way to force it to complete?

Best regards,

Nick

Hi Nick,

If your app is in Python, Go or PHP, did you enable warmup requests?

If you did, then you mean the app is in a migrated state because the new one isn't the default version yet? Or because your old version still serves? The older version should continue serving if your users type the version in your url.

Cheers

Hi Patrice,

It's a Python app, and yes warmup requests are enabled.

The app is stuck in the "migrating" state - the "traffic destination" has been in the "Traffic move is in progress" for 16 days. The radio buttons to change default versions are disabled so that I cannot change the default version, which is still the "traffic source".

Best regards,

Nick

Hey again Nick.

This is definitely peculiar. What I would suggest at this point is to open a Defect report on this page, and make sure to use the "Restrict-View-EditIssue" label. This way only you (the creator) and people from Google will be able to see it. On that issue, you can then give your appID, and we will be able to go investigate further and see what can be done. 

Cheers!

Thanks Patrice, now raised as issue 12134.

Best regards,

Nick

Hi Nick,

We've been investigating, and it seems like it went through recently. Can you confirm that?

We're looking at a root cause, but from what we can see, you should be done with the traffic migration.

Cheers

[Nick Clarey]

I'm afraid no change that I can see - still listed as "traffic move is in progress".

Best regards,

Nick

Hi Nick,

thank you for the quick replies. I just double-checked and I can confirm that it seems okay on our end when we check. Do you mind including a screenshot of what you see so we can investigate on how come there can be a discrepancy?

thank you in advance.

Hi Nick,

Sorry for the lack of reply or updates. This is just to let you know you are not forgotten and we've tried to figure out what was happening. We now have a better understanding of what caused your traffic migration to stop and it should be fixed relatively shortly.

I'll let you know whenever I have more news on that front.

Cheers!

Hi Patrice,

I'm going to need to update the application in the next week - is this likely to be resolved by then? Will an update to the existing migration destination work?

Best regards,

Nick

Hi Nick,

Thank you for your continued patience on this.

Unfortunately, the precise change to get your application "unstuck" needs to be done on the back end directly. Therefore, I just sent the request up and I'm waiting to see what happens with it, so an ETA might be hard to get. I'll try to put some more pressure on it to see what can be done to fast forward the process.

Do you have a precise date for your update next week? That'll help putting it within a more precise timeframe.

Cheers!

Hi Patrice,

In the next week = by Friday 31/7.

Best regards,

Nick

Hi again Nick,

After some discussions, I got traction on your issue and the backend team did some changes. On our end it now seems like it should be gone and your app should be fully migrated. Can you confirm if that is the case on your en as well?

Thank you

Cheers

[Nick Clarey]

Hi Patrice,

The application now appears to be fully migrated. Thanks!

Best regards,

Nick

Happy coding until Friday. I hope your next deployment goes well :)
