Both Cloud EPC and HSS servers are being upgraded on August 16, 2018, 12:00am Pacific. This is the same upgrade that was scheduled for last week. We delayed the upgrade to allow for more time for operators to upgrade the firmware on their CPEs. This upgrade mainly adds bug fixes and HSS failover support. Base stations running HaloB software will remain active. Downtime is expected to last around 2 hours.
Additional Notice: Please make sure that all outdoor Atom R9 Gen1 CPEs are upgraded to at least version BCE-ODU-1.0.12. For Atom (category 4) Gen2 CPEs, make sure they are upgraded to at least version BaiCE_AP_2.1.4_NA. There is a known issue in previous firmware versions that if the CPE disconnects from the MME server, there is a chance it may not attach to the same eNodeB until the CPE is rebooted.
