Bandwidth will be performing a maintenance to add capacity to our HTTP MMS Messaging product. This maintenance will build upon our robust infrastructure and enable Bandwidth to download customer MMS attachments from an expanded set of IP addresses.
There is no impact to HTTP MMS messages expected during the change, however, Bandwidth is advising customers to add the additional IPs to allow traffic prior to the completion of this maintenance. Customers may view the additional IPs here: https://support.bandwidth.com/hc/en-us/articles/360056770053
Bandwidth customers may reach out to their Customer Success Manager for further details via the bandwidth.com/support portal.
