Dear Valued Customer,

As part of GTMaritime's commitment to the continuous improvement of their systems and services, gtmaritime will be performing essential maintenance on our core infrastructure on Sunday 17th May 2026.

The maintenance will take place during a 2-hour window between 13:00 and 15:00, during which we anticipate a maximum of 60 minutes downtime.

We will, of course, endeavor to keep any disruption to an absolute minimum.

During the maintenance window:

• All portal and dashboard services will be unavailable, including the GTMaritime dashboard.
• Vessels will be unable to connect during this period. All messages and data transfers will be queued and automatically delivered once the maintenance has completed.

We apologize for any inconvenience you may experience with your communications during this service interruption.
If you have any questions, please do not hesitate to contact One Net Group Support (support@onenet.group, +357 25 828 999 "Option 1").
