My blog host provider has sent me the following notice

Maintenance Description:
TMNet has scheduled a repair and audit activities in the CBJ1 Data Center (formerly known as MyLoca) that involved the whole Data Center. It is part of an ongoing effort to ensure the integrity and reliability of the electrical power system of the Data Center at all times. The agenda of the planned outage are as below:
1. Power Upgrade (4x PDU + 4xSTS - to cater for capacity requirement)
2. Repair / audit /retest (to resolve major outage on 16/9 and 3 /10)
3. Batteries replacement (end of lifespan for 816 units UPS batteries need to be replaces)
4. Migration (re-cabling problematic power connection to new PDU/STS)
5. Installation of Monitoring Tools/probe and software
6. Megatest - assessment and audit 640 cables to the rack to check for fitness (detect harmonic /voltage drop or leakage.

Maintenance Impact:
The maintenance will begin at 07.00AM Malaysian Time on Saturday, 14th April 2007. The work is expected to conclude within 24 hours, at approximately 07.00AM Malaysian Time, Sunday, 15th April 2007.

During these 24 hours period of activities, the AC power supply will be totally shut off due to security measures. We have been advised by TMNet to properly shut down all our servers and equipments before the activities take place at the said time. As a result, all web sites and emails hosted on CBJ1 data center will be inaccessible during this planned maintenance.

Anyway, bottom line is - my blog will be inaccessible 7am (14th Apr) - 7.00am (15th Apr) GMT +0800
