Service Alert: Back-end Server Reboot

We are going to do an emergency reboot at 11pm tonight of one of our back-end mail servers.

The filing system has started to have some unusual delays. This happened to another server about a year ago and a reboot fixed it.

As this server has been up for 4 years, we suspect the same issue, so are going for the reboot option.

Apologies to all affected – outage on POP3 & IMAP for affected users should last around 10 minutes max if all goes to plan.

Service Alert: Zimbra Server Upgrades

Over the next week and a half we will be upgrading our Zimbra servers from version 8.7 to 8.8.

Work will commence at some point after 22:00 hrs on each day – with a possible downtime of up to 2 hrs, but we hope this will be significantly less.

The plan is to update the relevant servers on the following dates:

Zimbra002 on Thursday – 21st November, 2019

Zimbra003 on Tuesday – 26th November, 2019

Zimbra004 on Thursday – 28th November, 2019

We don’t expect to see any issues and any Outlook users should be prompted for a connector upgrade; if this doesn’t happen Outlook users will need to get the connector for 8.8.15 GA – available from the following link. If their Outlook is 32bit, then they will need to get the 32bit version.

Service Alert: Mail Server Reboot Last Night

Just a quick note to say that this was done at approx 23:15, and all seems OK today, but we will continue monitoring closely for a while.
