• Schedule: June 14, 2025 (Saturday) | 08:00 AM – 08:00 PM (PHT)

• Activity Details:

Hi Team,

Please be informed that one of our third-party providers will conduct a network maintenance and testing on June 14, 2025, from 08:00 AM – 08:00 PM (PHT) due to a recent incident that requires immediate action.

During the maintenance window, there will be a 12-hour test window, with a total downtime on one of our SMT Site to Datacenter Circuit. However, due to the configuration of our network having backup circuits, we expect only a partial impact on internet and network connectivity as we have automatic failovers in place.

During the failover process, you may experience brief disruptions on any of the following below:

Choppy or Dropped VoIP Calls – Poor audio quality, delays, or dropped calls on platforms like Zoom, Teams, or Skype. Delayed Emails & Messages – Slower delivery of emails (Outlook, Gmail) and messages in chat apps like Slack and Teams. Latency Issues – Delays in response times, particularly for real-time applications. Remote Desktop (RDP) Disruptions – Lag, session timeouts, or disconnections when accessing remote systems.

• Service Impact: Partial Impact on Internet and Network Connectivity
