LON01 – ESXi10 PSU – 12:10 – 26/12/2014 *CLOSED*

Our network monitoring has alerted us to a possable PSU failure
on ESXi10. This server has redundant supplys and remains online but in an “at risk” state.

Engineers are due to investigate shortly with the aim of restoring the supply remotely if possible should this be confirmed as being in a warning state.

Failed hardware will be replaced as soon as possable and the unit shutdown to protect adjacent devices.

UPDATE 01 – 13:00
An Engineer has remotely logged in to the OOB (out of bounds) management interface to get real-time hardware / status information from the server and has been able to confirm both PSUs are in an operational state.

We can only conclude ESXi is feeding our network monitoring incorrect data to our SNMP session.

Further investigation is required as to the cause of this, however we are happy the server is not at risk and closing this risk report

LON01 – 15/12/2014 – 20:00 till 23:00 *Planned Maintenance* *COMPLETE*

1) We will be making some changes to our VPS cluster to bring online additional capacity. Unmanaged 3rd party VPS sessions may see a small amount of downtime while there images are moved. No other impact is expected.

2) An audit will be conducted on our existing bulk fibre between our suite on the 4th floor and our meet me rack on the 2nd. This is for upcoming network expansion. No outages are expected however the links should be considered “at risk” due to the physical nature of the works. Should an outage occur on a fibre link then our network will automatically re-route traffic via a alternative path.

UPDATE01 – 23:30 These works have been completed as expected, However the 3rd party ESXi images will not be moved until 22:00 Tuesday night (16/12/14)
