The front-end to Mach’s Hosted Exchange platform was running much slower than normal but did not go offline (P2 SLA Incident). This affected the normal speed of email send/receive delivery from Email Clients such as Exchange or iPhone (root cause was a VMware software issue, which was resolved as quickly as possible by Mach making configuration changes to improve speed without causing services to actually go offline).
This issue commenced at 9.32am and precise ETA to complete was unfortunately not able to be accurately forecase due to the particular VMware issue.
However at 2.28pm Mach was able to successfully restore normal speed. We thank our customers for their patience as we resolved this issue in just under 5 hours without major outage or loss of any email.
