[Scheduled Infrastructure Maintenance – August 12, 2025]

Tue, 12 Aug 2025 05:00:00 -0000

Nodit will conduct scheduled infrastructure maintenance on Wednesday, August 12, 2025, from 05:00 to 07:00 UTC (14:00 to 16:00 KST). This maintenance is a necessary part of scaling our node pools to support more blockchain networks and further improve Nodit’s service reliability. While we are committed to ensuring uninterrupted service during this period, there may be a brief (<1 second) packet loss during firewall fail-over. In rare instances, this could cause minor block synchronization delays for some network nodes. We appreciate your understanding as we carry out this essential upgrade to deliver an even better experience for all users. Please be aware of this possibility and consider it in your node operations and monitoring. Thank you for your understanding and continued support. — Nodit Team
