UPDATE 3:27, December 23, 2017: SirsiDynix has resolved the issue that caused Enterprise to go down. Apparently, an issue at their data center in Atlanta caused an outage for numerous customers. Enterprise is now functioning normally. Thanks to SirsiDynix for fixing the problem but, more importantly, thank YOU for your patience today.
The Enterprise public access catalog is down. We have contacted SirsiDynix emergency support and they are investigating; it looks like a number of their customers are suffering the same issue. We will post further information as the situation develops.
