- 13:05 MST: The ECSU data from Feb 21, 22, & 23, 2007 was corrected today for the clock drift that occured on those 3 days. -Afshin Andreas
- 13:20 MST: The 2 minute timeout for external users when requesting a large custom ZIP file (from daily, monthly, site comparison, or solar position) has been fixed using an undisclosed work around. -Afshin Andreas
- 14:28 MST: The NREL Proxy server was recently reconfigured with a two minute timeout. MIDC users could be affected by this if they request a large custom ZIP file (from daily, monthly, site comparison, or solar position) that takes longer than two minutes to create. The result will be an Error 502 Bad Gateway after 2 minutes have elapsed. Internal NREL users can avoid this problem by using the internal MIDC server. External users will have to select a smaller time range, until a solution is found. -Afshin Andreas
- 10:32 MST: The ECSU datalogger clock was fell behind 4 hours and 20 minutes on 2/21/07. Clock was reset today at 12:25 EST. Data will be corrected sometime within 30 days. -Afshin Andreas

- 09:46 MST: December 2006 Monthly Data Sets & Reports for ECSU has been generated. -Afshin Andreas
- 09:33 MST: December 2006 Monthly Data Sets & Reports/Plots for SRRL BMS have been generated. -Afshin Andreas
- 10:57 MST: Due to communication issues created with a recent upgrade of LoggerNet and the aging SRRL BMS CR23X datalogger. The CR23X had to swapped out with a spare unit on January 12 from 13:18 to 13:35 MST. Several instrument will read missing or bogus during that time. -Afshin Andreas
- 08:12 MST: The was another power outage the NWTC M2 shed last night from 17:23 to 19:58 MST. A new UPS or battery still needs to be purchased. -Afshin Andreas
- 16:06 MST: As of 14:58 MST today, the MIDC server is now duplicated to a new public server. NREL users can still access the internal MIDC server, which is required for special data sets labeled as "NREL or Internal Only". Note: There could be up to a 1 minute delay before data appears on the public server, therefore internal NREL users should use the internal server if quicker data access is desired. -Afshin Andreas
- 14:22 MST: Communcation to the NWTC M2 datalogger was re-estabilished yesterday @ 17:47 MST. There was a power outage and the building's UPS had failed. -Afshin Andreas
