IRIS Real-Time server (RTSERVE) users:

Be aware of potential hopefully short outages on some networks that IRIS receives from USGS over time period:

Friday July 24th, 18:00 to Monday July 27th 01:00 UTC.

Potentially affected networks:
AV C0 CU GM GS
GT HV IC IM IU
IW MI N4 NE NM
NQ NW PT RO US
XU YX

Here is the notice from USGS:

==========================================

Dear Users of USGS Seismic Waveform Services:

Please note the following announcement. We appreciate your patience during this transition.

Best Regards,

David Mason

U.S. Geological Survey, National Earthquake Information Center

Event Description

The Department of Interior will physically move their Internet gateway at the Denver Federal Center to a different location on campus.

Time

Friday July 24th, 18:00 to Monday July 27th 01:00 UTC.

Expected Impact to USGS Waveform Services

Internet connectivity for the National Earthquake Information Center and its public waveform services at the DFC will be failed over to an alternate gateway near the start of the maintenance window. As equipment are moved during parts of the work, requestors of real-time feeds from USGS waveform servers can expect “short” outages. Additionally, due to added load through the alternate gateway, users may also experience slow or delayed connectivity. There are no workarounds to this potential degradation.

Organizations who receive data from USGS over dedicated lines should expect to see these effects over those circuits, due to the upstream impacts of the maintenance.

The outage will affect some station networks differently from others. For example, about a dozen GSN stations (subset of IU network) received through the CTBTO infrastructure are expected to go down hard throughout the window and subsequently backfill. However, we expect that most networks should not experience this severity of degradation.

Most data will backfill within hours once the work has been completed. With regard to the SeedLink server (137.227.224.97, 18000), real-time data should immediately become available, though it will be mixed with older data as they backfill over the course of some hours.

Contact Information

Should you continue to experience unusual delays or outages of these services following the above time window and backfill estimates, please contact me and cc ketchum<at>contractor.usgs.gov and bmielke<at>contractor.usgs.gov.
