Summary

We are moving from Data Centre model to Cloud Compute model to reduce risks, enable flexibility and scalability in technical operations.
Calling has been migrated to cloud. No actions or attention is required.
SMSs are yet to be migrated. We are recommending using sms.phonon.in instead of c4c.phonon.in to send SMSs before 15 April 2021

Does it impact me?

If you’re receiving this email, and you are sending SMSs, we need your attention and action for a minor change. There are no major impact on any services.

Why are we making these changes?

We have a business risk with our existing data centre belonging to Reliance Communications DAKC. NCLT has begun bankruptcy process for Reliance Communications^[1] and therefore we are proactively moving our operations out.
Using this opportunity, we are accelerating our plan to move from data centre model to cloud compute model
By being a complete cloud solution, it enables us to:
1. Scale up rapidly as we need
2. Improve the processing power of our applications
3. Have a more reliable, flexible and secure infrastructure

What are the changes?

We are transitioning our services from Data Centre model to Cloud Computing model and therefore moving our services from the Mumbai DAKC Data Centre to AWS Cloud Compute, at Asia Pacific - Mumbai (ap-south-1) location.

How does it impact me? What do I need to do?

Change SMS gateway domain
1. Now with the calling applications going online if you use c4c.phonon.in the operations will be delivered from AWS Cloud and SMS services are yet to be migrated. And therefore to disambiguate between the two we are recommending usage of sms.phonon.in instead of c4c.phonon.in to send SMSs.
