[ensembl-dev] Querying BioMart with XML

[Thomas Maurel]

Dear Jerry,

I am happy to report that your mart xml query is still valid and working. I am afraid that we have experienced some intermittent issues with BioMart recently so I am sorry about this. Please note that our website is still working with reduced functionality, please see more information here: http://www.ensembl.info/2020/02/18/reduced-functionality-16th-25th-march-2020/ <http://www.ensembl.info/2020/02/18/reduced-functionality-16th-25th-march-2020/>.

Hope this helps,
Kind Regards,
Thomas
