1. [SRA] 2017-06-19:   Access to SRA Has Been Restored (more...)(less...)

On Friday, June 16, 2017, the National Library of Medicine experienced a hardware problem that resulted in the shutdown of the SRA's primary data center. Although the hardware problem was addressed within hours and most services were restored, a few servers continued to experience network issues until this morning, June 19th.

Service was restored as of 9:20 AM EDT.

If you experience any problems accessing the SRA, please write to us at sra@ncbi.nlm.nih.gov.

2. [SRA] 2017-02-07:   HTTP(s) Access to SRA Has Been Restored (more...)(less...)

If you experience any problems accessing the SRA, please write to us at sra@ncbi.nlm.nih.gov.

3. [SRA] 2017-02-06:   SRA Downloads Unavailable (more...)(less...)

Starting on or about February 6th 2017 at or before 2:10 PM EST, NCBI network services to the SRA began to fail and are either sporadically working or completely unavailable.

We are working to resolve this issue, and apologize to everyone for the disruption.

4. [SRA] 2016-09-28:   HTTP(s) Access to SRA Has Been Restored (more...)(less...)

Service was restored at approximately 3:40 PM EDT.

Starting on or about September 28th 2016 at 2:00 PM EDT, NCBI network services and the SRA began to fail and are either sporadically working or completely unavailable.

5. [SRA] 2016-09-28:   Unavailability of SRA over HTTP(s) (more...)(less...)

Starting on or about September 28th 2016 at 2:00 PM EDT, NCBI network services and the SRA began to fail and are either sporadically working or completely unavailable.

We are working to resolve this issue, and apologize to everyone for the disruption.

6. [SRA] 2016-06-11:   HTTP Access to SRA Has Been Restored (more...)(less...)

Service was restored at approximately 5:45 PM EDT.

Starting on or about June 10th 2016 at 5:10 PM EDT, a scheduled update to SRA servers created a disruption of access via HTTP. This caused the SRA Toolkit and other tools that use on-demand retrieval from the SRA to fail.

7. [SRA] 2016-06-11:   Unavailability of SRA over HTTP (more...)(less...)

Starting on or about June 10th 2016 at 5:10 PM EDT, a scheduled update to SRA servers created a disruption of access via HTTP. This will cause the SRA Toolkit and other tools that use on-demand retrieval from the SRA to fail. Some of the failures may be immediately visible, others may be more subtle.

We are working to resolve this issue, and apologize to everyone for the disruption.

8. [SRA] 2016-04-11:   Intermittent SRA Network Failures (more...)(less...)

Starting on or about April 1st 2016, NCBI experienced intermittent network access failures that resulted in occasional inability to locate SRA objects and in some cases inability to access them. Typical failure messages might report 'file not found while opening file within network system module’ or ‘access prohibited’ errors. The problem is not with your software (SRA Toolkit or NGS APIs). We believe these issues have been addressed, but encourage anyone experiencing trouble to write to us with a report.

9. [Trace Archive] 2013-12-10:   Trace Archive Maintenance Schedule (more...)(less...)

We reserve the right to shut down the services for maintenance procedures on a second Tuesday of every even month between 10 AM and 4 PM EDT. Next maintenance is scheduled for February 11, 2014.

10. [Trace Archive] 2013-10-08:   Trace Archive Maintenance Schedule (more...)(less...)

We reserve the right to shut down the services for maintenance procedures on a second Tuesday of every even month between 10 AM and 4 PM EDT. Next maintenance is scheduled for December 10, 2013.

11. [Trace Archive] 2013-08-13:   Trace Archive Maintenance Schedule (more...)(less...)

We reserve the right to shut down the services for maintenance procedures on a second Tuesday of every even month between 10 AM and 4 PM EDT. Next maintenance is scheduled for October 8, 2013.

12. [SRA] 2013-06-19:   Update to SRA-BLAST. (more...)(less...)

SRA-BLAST has undergone a dramatic update, both in terms of user interface and search performance.

SRA-BLAST now includes:

  • Targeted searching within one or more SRA Experiment sets (i.e., "SRX accessions"). Users may now search combined datasets of up to 2 billion individual reads.
  • An "autocomplete" feature that will allow users to specify SRX accession, SRX title, organism scientific name, or tax id to help build the search set.
  • Data obtained from Roche 454 and newer Illumina instruments (HiSeq and MiSeq) are now included in the SRA-BLAST database, owing to longer read lengths from these technologies.
These updates to SRA-BLAST make it an even more useful tool for searching through the more than 700 trillion open-access bases currently housed within the SRA.

13. [Trace Archive] 2013-06-11:   Trace Archive Maintenance Schedule (more...)(less...)

We reserve the right to shut down the services for maintenance procedures on a second Tuesday of every even month between 10 AM and 4 PM EDT. Next maintenance is scheduled for August 13, 2013.

14. [Trace Archive] 2013-05-31:   Trace Archive Maintenance Schedule (more...)(less...)

We reserve the right to shut down the services for maintenance procedures on a second Tuesday of every even month between 10 AM and 4 PM EDT. Next maintenance is scheduled for June 11, 2013.

15. [SRA] 2013-04-08:   SRA Software Toolkit 2.3.2 has been released. (more...)(less...)

NCBI has released SRA Toolkit 2.3.2. This version fixes some bugs in the previous releases for remote access to SRA files including access to Authorized Access files. This version also includes a GUI Java configuration interface that can be run from X-Windows on Linux.

Users can download the latest software from NCBI SRA software page. For technical assistance please contact the SRA Development team at sra-tools@ncbi.nlm.nih.gov

16. [SRA] 2013-03-08:   SRA Software Toolkit 2.3.1 has been released. (more...)(less...)

NCBI has released SRA Toolkit 2.3.1. This version eases remote access to SRA files including compressed aligned sequence files that previously required downloading their reference files, by automatically downloading the needed data and files. The new version also includes a GUI Java configuration interface that can be run from X-Windows on Linux, and enhancements to previously released binaries.

Users can download the latest software from NCBI SRA software page. For technical assistance please contact the SRA Development team at sra-tools@ncbi.nlm.nih.gov

17. [SRA] 2012-12-12:   SRA Software Toolkit 2.2.2 has been released (more...)(less...)

NCBI has released SRA Toolkit version 2.2.2. This release includes minor bug fixes to previous release version 2.2.0.

SRA Toolkit precompiled binaries and source code are available from the Software page on the SRA web site. For technical questions please contact the SRA development team sra-tools@ncbi.nlm.nih.gov

18. [SRA] 2012-12-12:   Scheduled SRA Service Interruption (more...)(less...)

SRA data submissions and retrievals will be interrupted starting on December 14th from 9 am until December 16th at 5 pm, due to scheduled maintenance. Entrez and SRA search will continue to function during this time. Please schedule your submissions and downloads accordingly.

19. [Trace Archive] 2012-12-11:   Trace Archive Maintenance Schedule (more...)(less...)

We reserve the right to shut down the services for maintenance procedures on a second Tuesday of every even month between 10 AM and 4 PM EDT. Next maintenance is scheduled for February 12, 2013.

20. [SRA] 2012-11-21:   SRA Software Toolkit 2.2.0 has been released (more...)(less...)

NCBI has released SRA Toolkit version 2.2.0. This release includes the Complete Genomics loader tool and three new tools: vdb-encrypt, vdb-decrypt and vdb-validate.

vdb-decrypt and vdb-encrypt now run recursively on directory contents and can perform their operation "in-place", rather than creating a copy. vdb-validate combines sra-dbcc with nencvalid. It will recursively analyze directory contents. At this point it only knows how to validate encrypted files and vdb (SRA) objects.

SRA Toolkit 2.2.0 precompiled binaries and source code are available from the Software page on the SRA web site. For technical questions please contact the SRA development team sra-tools@ncbi.nlm.nih.gov
