In July 11th we will be replacing all of our Mumbai servers with new NVMe hardware running on our own network. The full schedule is below, including the new IPs for all servers. There will also be new server hostnames however the old hostnames will be repointed.
If you do not use our DNS we recommend using a CNAME to the server hostname where possible (especially for MX entries). This way you do not need to make any changes.

Unless otherwise mentioned all migrations will take place between roughly 3pm and midnight UTC. Larger accounts may need more time to migrate.

s613.bom9[Indian DC Cloud-1]: 69.57.172.42 Tuesday July 11th
Please note the old system IP will proxy HTTP requests to the new one to help with cases whereby changing DNS can require some time.
