IT Services Alerts - DNS server maintenance work, 8.30am-9am, 23rd & 30th June
IS Services will be performing routine maintenance on the TCD DNS servers on 23rd and 30th June between 8.30am and 9am. These servers are used to lookup computer and websites addresses on the internet. The College has a multiply-redundant DNS service, meaning there are still two operational DNS servers when one DNS server is offline, and so no interruption to services for end users is expected during these upgrades.
If there are any TCD servers outside of IS Services that have not been configured correctly to reference more than one TCD DNS server then this work could result in disruption to the services hosted on those mis-configured servers.
