Starting at 10PM this evening, the SMTP server(s) responsible for local email delivery will undergo an extremely brief maintenance window, during which time sending mail from on-campus will not be possible. The entire outage is expected to be on the order of minutes. Both checking mail (POP/IMAP), and receiving mail from off-campus domains, will not be affected.
It is generally believed that we have located and corrected problems causing network stability issues. There will likely be residual fallout for a short while as systems accustom themselves to a full-network restart, but all network metrics have achieved normality.
Helios experienced a system fault and required a reboot, all services should now be available.
There will be outages lasting 2-3 minutes of all network segments impacting most/all of the campus, as technicians work to locate the source of a network problem. Save early. Save often.
We are receiving reports of intermittent network connectivity issues across campus. Technicians are aware of the issue and are looking into it.
Recent Helios instability in the wee hours of the morning is causing inconsistencies in the user backup sets (_backup folders). For those users who have critical data on Helios, and for which they consider backups necessary, CTS is encouraging the use of additional personal backup copies of said data until the situation stabilizes. Technicians are working diligently to correct the issue.
Helios will be going down for a brief maintenance window starting this evening at 11PM. Window expected to be less than 10 minutes.
The mail queue cleared out by 6PM, and all mail is caught up and moving normally with no delays.
The campus Internet email exchanger is experiencing problems, leading to delays receiving email incoming from the Internet. Sending or receiving mail locally, or sending to off-campus addresses is not affected.
The campus webserver experienced application-level anomalies which caused all hosted web resources to be sporadically/completely unavailable throughout the morning. These anomalies have resolved themselves and all web resources should now be available.
