Performance Degradation and Outage - Wholesale
SHORT DESCRIPTION:
Intermittent access of MOS MUI links through TML on November 9, 2008
INTENDED AUDIENCE: All
Market Participants
DAY AFFECTED: November
9, 2008
LONG DESCRIPTION:
A performance degradation and outage occurred on Texas Market Link (TML)
servers which prevented some users from linking to the Market Operating System
(MOS) Market User Interface (MUI) web pages from approximately 8:15 AM to 11:28
AM on November 9, 2008. The MOS MUI links on TML included QSE Schedule
and Bids, and Market information.
The performance degradation occurred during a
temporary web server failover, where some users experienced intermittent errors
when accessing the MOS market links. Example error messages included
"system not responding," "page cannot be displayed," and
"page under construction." The root cause is under
investigation. An outage on the TML servers also occurred from 10:57 AM
to 11:10 AM due to network issues resulting from the planned maintenance window.
