ALERT: MMS Public IP Addresses are Changing



As a result of a network migration from AWS Classic networking to AWS VPC networking, the public-facing IP addresses of MongoDB’s services, including both JIRA ( and MMS ( and, will be changing on Thursday, January 29, 2015 (16:00 UTC / 11:00 EDT).

The current IP addresses and new IP addresses are documented (along with a procedure for making a seamless change, if you have them hard-coded anywhere) here.

This will only impact Customers that * are using DNS TTL overrides, * have our IP addresses hard-coded into one or more of their systems * or have firewalls controlling outbound access to those IP addresses.

Workarounds In the scenario where there is a hard-coded IP address, it will need to be changed on Thursday, January 29, 2015 (16:00 UTC / 11:00 EDT) or access to our systems will be degraded once the IP address change has been made. Please also note that the old IPs will be decommissioned shortly after and at that point access will be lost completely until your systems are updated.

Firewalls can add both sets of IP addresses in advance, and then remove the old IP addresses once the change has been made. DNS servers should be adjusted to honor the TTL returned during this process, or will need their caches manually cleared once the change has been made. Hard-coded IP addresses in applications should be switched to use DNS or will need to be manually adjusted post-change.

If you have any questions about this change or need help implementing any workarounds on your systems, feel free to file a ticket in JIRA prior to the change date and we will work with you to make sure that your team can make the appropriate updates on your side.

Thank you!
