• Event: Data Link Layer Testing

• Schedule: June 28, 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 28, 2025, from 08:00 AM – 08:00 PM (PHT) due to a recent incident that requires immediate action.

Please be advised that during the maintenance window, a 10-hour testing period will take place, which will result in a total downtime on one of our SMT Site to Datacenter circuits. 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

• Event: Windows Servers Patching Activity

• Schedule 1: June 28, 2025 (Saturday) | 09:30 AM – 02:30 PM (PHT)

• Service Impact: Windows Servers – All Sites

• Event: Additional High Availability Deployment

• Schedule: June 28, 2025 (Saturday) | 04:00 PM – 05:00 PM (PHT)

• Activity Details:

Hi Team,

As part of our ongoing efforts to enhance network redundancy and improve overall system reliability, our team will be implementing an additional high availability deployment to minimize the risk of service interruptions

During the maintenance window, we anticipate minimal to no impact on internet and network connectivity.

Automatic failover mechanisms are in place to maintain uninterrupted service and ensure business continuity.

We will continue to monitor the network closely throughout the process and will provide updates if any unexpected issues arise.

• Service Impact: Minimal to no impact on Internet and Network Connectivity

• Event: Optical Fiber Cable Replacement

• Schedule: June 30, 2025 (Monday) | 10:00 AM – 10:00 PM (PHT)

• Activity Details:

Please be informed that our service provider will be conducting a fiber optical cable replacement that hosts our circuit.

During the maintenance window, a latency increase on the IPLC is expected. However, due to the way our network is setup, traffic should be automatically failover to the VPN connection that will result to a latency increase on VPC/RDP’s.

• Service Impact: Latency Increase on IPLC VPC

• Event: Network Device Software Upgrade

• Schedule: July 06, 2025 (Sunday) | 01:00 AM – 06:00 AM (PHT)

Hi Team,

We would like to inform you that one of our service providers will be performing a service migration to a new platform, along with a software upgrade of their network devices. This initiative aims to enhance network security, improve performance, and ensure overall system reliability.

During the maintenance window, a maximum of two (2) hours of interruption is expected. 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 Internet and Network Connectivity Interruption
