Welcome to Bandwidth's home for network updates. Here, you will find information pertinent to outages, scheduled maintenance, and general notices with real-time updates.
Bandwidth will be performing our quarterly Call Assure testing. This is a proactive exercise to periodically validate the processes and procedures are ready if and when a need arises to invoke this capability.
During testing, all toll-free origination traffic will be delivered via the Call Assure network. At the conclusion of the test, traffic will return to its normal routing process. Some toll-free features may not be available for the duration of the testing.
If you have any questions or need additional clarification, please reach out to our Customer Success Team via the bandwidth.com/support portal. Posted on

Bandwidth will be performing scheduled maintenance in the global Belgium data center. As a part of the maintenance, with the intent of minimizing impact to voice services, Bandwidth will be removing voice traffic from the global Belgium data center, redirecting traffic to geo-redundant global data centers. As a result of the traffic removal, customers may observe their voice traffic being routed to/from them through our geo-redundant global data centers. Customers connecting directly to the global Belgium data center may also elect to proactively re-route their traffic to our geo-redundant data centers to avoid any possible disruption to services. The following services will encounter interruptions during the maintenance: International & US Number searching, ordering, and porting - Bandwidth App Messaging - VoxSMS Legacy Global Portal
