Outages

Intermittent service on diamond due to heavy I/O (backups running during the day)– Dec 17 1114-1202 (48min)– Dec 18 1247-1252 (5min)– Dec 19 1517-1527 (10min)– Jan 7 1122-1247 (85min)

Intermittent service on 33% of CAH servers due to runaway client from application at library– Jan 4 1525-1542, 1607-1608 (18min)

POP service on garnet spotty on 12/17 due to problems during certificate renewal (chaining)

AutoFiled Folder Issues Outlook Express 6, Eudora, and

Pegasus have problems accessing AutoFiled folders– Workaround: Use GopherMail

Thunderbird: be sure to enable Allow server to override these namespaces

Outlook and OS X Mail: be sure the IMAP root setting is left blank

AutoFiled Folder Issues (cont.) New managers page option added to

allow for symbolic link creation Pro: allows user to see AutoFiled folders Cons:

– Service interruption on AutoFiled server (while rare) would result in general IMAP interruption

– When used with clients which DO honor namespaces, AutoFiled folders would be displayed twice

UMCal Archiving

Expiring calendar data monthly starting as early as 2/1

Keeping 18 months Older data kept at least 7 years

– Made available on request (ICAL format)– Clients such as Mozilla Sunbird, Outlook,

and Mac ICAL can import these files– Making available via web is not practical– Loading these files into the UMCal client is

NOT supported Necessary for performance reasons

Self-serve password reset Available for student accounts

only May eventually be allowed for

other account types Pilot starting mid-January Production rollout is anticipated

by the 2nd week of the semester
