Service Impacting Updates to Flowroute Edge Proxy HK PoP in 2022

Email communication about Hong Kong Edge Proxy Migration. 

Date of sending: April 14, 2022.

From: Flowroute Team,

Subject: ACTION REQUIRED: Hong Kong Edge Proxy Migration - June 14, 2022


In order to continue providing you with quality and reliability to our 100% cloud-based service, we are updating the current Edge Proxies. This means we are changing the IP ranges to suit the new equipment. To complete the move, Flowroute is changing IP ranges on AP-East-HK Edge Proxy (EP/PoP).

WHEN? June 14, 2022 (Exact time will be announced next month)

IMPACT: This change will affect any PBX which directly specifies the AP-East-HK EP by IP address or has cached DNS records. If your PBX is resolving DNS SRV records then you will only need to whitelist the new IPs. If you are directly calling the IP address then you will need to update your PBX with the new IP addresses.
Affected Edge Proxy Information:
FQDN (no change):
Old (current) CIDR:
New (future) CIDR:

NOTE: In-flight calls will be unaffected. The IP range change of Hong Kong Edge Proxy will be permanent and will not be restored at a later date.

ACTION REQUIRED: Edge proxies found on Flowroute Interconnection page will need to be added to your current firewall whitelist. You’ll need to whitelist the new IP range before June 14, 2022, to make sure your PBX is ready to receive inbound calls from the new IPs. We’ll be announcing the exact time frame IP range is changing in the next email communication.
