Alternative Biomart Hosts

Question

I am trying to run the following Biomart script

(params$species == "rabbit"){
    ensembl = useMart(biomart="ENSEMBL_MART_ENSEMBL",
                  dataset="ocuniculus_gene_ensembl", 
                  host="uswest.ensembl.org",
                  ensemblRedirect = FALSE)
    orgSymbols <- unlist(getBM(attributes = 'ensembl_gene_id', mart=ensembl))
    mart <- useMart(dataset = "ocuniculus_gene_ensembl", biomart='ensembl', host="uswest.ensembl.org")

The host keeps timing out - does anyone know another host URL I could use?

Thank you
