NOAA ‑WAVE Network Maintenance
NOAA N‑WAVE will perform vendor router replacement at College Park (CLPK) on two consecutive nights:
- The first night of maintenance will be from 6-11 p.m. ET on Tuesday, April 7.
- The second night of maintenance will be from 6 p.m. ET on Wednesday, April 8 and ending at 2 a.m. ET on Thursday, April 9.
Intermittent connectivity disruptions may occur; however, USPTO is expected to remain reachable via alternate connections.
During the maintenance period, users may experience brief disconnects, occasional sign‑in errors, and possible latency when accessing internal or external applications.
Users will need to complete critical tasks before the maintenance period. If issues occur, wait a few minutes and reconnect. Please contact the designated support point if the issue persists.
