Not able to access bigdata lab


I am not able to login to bigdata lab. Kindly check. Thanks

Kindly let me know, if there is any issue with the lab as I am not able to login since yesterday evening.


What is your login id to the lab?

My user id is subramanyamsibbala



I am ok to have the new id created with name s_subbu, if the issue does not resolve and it is with the id. Weekend is slightly crucial for me to complete the practicals.


No need to have another user. You login and password are working fine.

Hi Durga sir,

I am still not able to login. I am using google sign in to login to the lab. It was working fine till friday night. From saturday morning onwards stopped working.
After clicking on google sign-in it opens up a new browser that tries to connect but at the end it stalls with white screen and not moving forward from there.

Kindly help, If there is any cookies issue or if I am missing any. I am targetting to give the exam by this monthend for which the access is compulsary.

Thanks in advance.
