[ensembl-dev] Error returned when using GRCh37's BioMart MartService

[Bruno Grande]

Hello,

I'm attempting to download data using GRCh37's BioMart MartService REST API
(using XML Query). I've successfully used this exact approach 2-3 months
ago. However, my recent attempts return errors.

Yesterday, BioMart was down. Now that it's back up, I'm getting the
following error:

Query ERROR: caught BioMart::Exception::Database: Could not connect to
mysql database ensembl_mart_80: DBI
connect('database=ensembl_mart_80;host=ensdb-5-g-03;port=5637','ensro',...)
failed: Can't connect to MySQL server on 'ensdb-5-g-03' (111) at
/ensemblweb/grch37/wwwmart/www_80/biomart-perl/lib/BioMart/Configuration/DBLocation.pm
line 98.

You may see this error for yourself by visiting this URL

(my
GET request with the XML query). Note that this only happens when I use the
GRCh37 API (http://grch37.ensembl.org/biomart/martservice/), but it works
with the latest API (http://www.ensembl.org/biomart/martservice/).

Any ideas as to why the GRCh37 API is returning an error? Do you think it
has something to do with BioMart being down yesterday?

Thanks,
Bruno
