Unisys Weather Web Outage: June 10-11

Unisys Weather experienced a major outage with our internet provider on Monday, June 10 at approximately 5:45pm EDT. An issue was identified with a major fiber optic cable in the Philadelphia area, knocking out access to our web servers including several data servers at the WeatherMax. Unisys data distribution on our backup circuits and satellite broadcast were not affected. Access was restored at around 5:40am EDT on Thursday, June 11. Customers are advised to use the toll free support phone number to report issues, as this outage also affected e-mail services.

Unisys Weather Data Center Maintenance 12/4/12

To all Unisys Weather Customers:

Beginning Tuesday, December 4, 2012, Unisys will be performing a planned maintenance action to upgrade the critical power systems at the Malvern, PA facility used for the Unisys weather data center. This important upgrade will include installation of new power sub-systems to replace aging units that feed Unisys Weather Information Services (UWIS) data center (aka WeatherMAX).

Unisys Weather will need to power down all primary, backup, and spare systems supporting WeatherMAX. In order to minimize the length of outages, we have performed careful planning and preparation. The WeatherMAX equipment will be powered down twice on Tuesday, December 4, 2012.

Date/Times of Outages:

- Approximately 7:00am EST (12:00 GMT) on Tuesday, 12/4/12 – Primary and backup systems for WeatherMAX will be powered down for 15 to 45 minutes to move these systems off of the primary power feed in order for Unisys to perform upgrades to the power sub-system.

- Approximately 5:00pm EST (22:00 GMT) on Tuesday, 12/4/12 – Primary and backup systems for WeatherMAX will be powered down for 15 to 45  minutes to move these systems back onto the upgraded power circuit.

Impacts to Users:

- All Unisys Weather customers on FTP/LDM and Web access.

- All Unisys NOAAPORT Gateway with 5th channel (Unisys commercial satellite channel) and/or landline connections to WeatherMAX

**Note: Customers receiving NWS/NOAAPORT data from the Government broadcast using the Unisys NOAAPORT system will not be affected.**

Due to the nature of the power system upgrade, all systems (primary and backup) will be moved at the same time. This scenario was chosen to provide the smallest window of outage.

In the event of a NOAA/NWS Critical Weather Day, this upgrade will be postponed.


Unisys NOAAPORT Gateway

• System architecture designed and built for real-time and very highly reliable delivery of weather information
• System tested for the future three-fold increase in data bandwidth requirements
• Weather industry standard communication protocols and data formats
• Added commercial weather products available to weather information consumers
• Delivering essential weather data and information at less cost

The Unisys NOAAPORT Gateway system is a fully integrated system that is configurable to receive the NWS NOAAPORT broadcast data stream, to receive the Unisys Weather data stream (satellite or landline), or receive both the NOAAPORT and the Unisys Weather data streams through diverse communication paths. The Unisys NOAAPORT Gateway is built, tested, and shipped from our Malvern, Pennsylvania based Weather Data Center and provided as a turn-key system fully capable to receive the 30 Mbps NWS broadcast. The system is built on an Intel platform using CENTOS or Red Hat 5 as the Linux operating system, and supports up to 32 simultaneous users. Users connect using TCP/IP choosing between three protocols: LDM, Unisys WXP, or Unisys GWIP.

Each NOAAPORT Gateway is configured based on the customer’s needs. Users may elect to receive the NOAAPORT only, requiring hardware and associated cabling to an external satellite receive station. Users acquiring the full NOAAPORT Gateway including the Unisys WeatherMAX data stream will have an option to connect to the Weather Data Center via landline. The landline option provides a redundant connection with automatic failover capability if landline service is degraded or interrupted.

The Unisys NOAAPORT Gateway ingest and processing functions are fully configurable to allow users to select products based on their needs. Alerts can be generated using Product Arrival Notification (PAN) messages, allowing users’ systems to process high priority products such as NWS advisories or warnings.

Commercial weather products, such as Unisys weather radar mosaics and VAR lightning data, are also available via the Unisys WeatherMAX data stream.

For enterprise missions, Unisys delivers weather information at less cost than customers building and maintaining their own services to receive information directly from the NWS and/or other sources of weather information. Unisys monitors the services and provides 24×7 support to assure high reliability of weather information delivery.
