CML Response Time

[T.Golbach]

Hi,

there are too long response times from the CML Server (10.10.20.50, 10.10.20.161). Can you fix the problem please?

Kind regards, Thomas

Something is happening on the back end for sure. Beyond massive lags.
I tried changing the ISP link on my side to verify it is not my device. Definitely something on Devnet backend. 

Pinging 10.10.20.50 with 32 bytes of data:

I saw this thread https://community.cisco.com/t5/devnet-sandbox/sandbox-doesn-t-work/m-p/5281452#M11116 looks like latency issues over the VPN. I am sure the team is investigating. Would check back later.

[AntonioGabor]

If I ping from 10.10.20.50 to 10.10.20.161 also unusually high latency over 400ms so that would indicate issue that is not vpn related.

I see, so this could be an internal issue the team is having.

I did a trace just there:

Also now there is now following warning:

[WairissonGomes]

Definetely something is wrong, I have been trying to access Cat Center Reserved Lab there is a huge packet loss, I tried to use a VM in the USA, near Cisco DC but the result is the same, can't get access to CML, ISE or CatCenter. 

[bigevilbeard]

@WairissonGomes I see there is unplanned maintenance on the sandbox right now.

[WairissonGomes]

Thanks for your response, now the maintenance message is gone but I am still experiencing 50% packet loss to cml node via sandbox.

[T.Golbach]

Still not working

[bigevilbeard]

Team could be working on clearing the issues still. I have not seen any updates.

[abhishekkumarrakeshkumarmishra]

Please let us know if there is any update on it ?

I am also facing the problem as well

[WairissonGomes]

It seems they have fixed the issue, now it is ok, no packet loss.
