Emergency Backup BLAT Servers

In case all/some blat servers go down, there is one backup blat server that hosts the "top 5" blatted assemblies. See below for current list of the backup server with port numbers:

hg38 trans started on blat4d port 17786, untrans started on blat4d port 17787
hg19 trans started on blat4d port 17778, untrans started on blat4d port 17779
hg18 trans started on blat4d port 17782, untrans started on blat4d port 17783
mm10 trans started on blat4d port 17780, untrans started on blat4d port 17781
mm9  trans started on blat4d port 17784, untrans started on blat4d port 17785

If the current blat server(s) hosting any of these 5 assemblies goes down, we will need to make the switch to this fail-over server. This is not an automated process; the hgcentral.blatServers table will need to be hand-edited.
