    2/27/05 - DLLSTX4 Site-Wide Maintenance

    This only affects our VPS servers.

    Greetings,

    On Sunday, Feb 27, 2005 Planet Engineering will be conducting site-wide network maintenance beginning at 11:59PM local time (US-Central - GMT-0600) to cut site traffic over to the new redundant fiber ring directly between the DLLSTX4 and the DLLSTX3 Internet POP site. The systems are already in place and currently being tested to ensure that the ring is operating without issue prior to cutover.

    The work will be done in 3 phases:

    Phase 1 - Routing protocols will be enabled on the new links connecting the two datacenters. Once the protocols are up, traffic will naturally start flowing across the new links to DLLSTX3 for Internet destined traffic, and across the existing links for traffic between the DLLSTX2 and DLLSTX4 datacenters. During this phase, it is possible that our end users will experience some latency and packet loss as the new routing paths are brought online.

    Phase 2 - After establishing that all is well (approximately 30 minutes) on the new circuits, engineers will be upgrading the existing fiber systems between the DLLSTX2 and DLLSTX4 datacenters. Tests so far have shown that traffic is uninterrupted during the upgrade, however it is possible that direct DLLSTX2-DLLSTX4 connectivity might be affected. If this occurs, traffic will flow across the new links without issue.

    Phase 3 - After the upgrade, connectivity will be checked once more to insure that all is functioning normally. Assuming all systems show normal, the work will be completed.

    The total time scheduled for the work is 2 hours. The total time expected for the work to be completed is less than 45 minutes, during which time little to no downtime is anticipated. The extra time is to allow Planet engineers time to troubleshoot any issues that could manifest during the work.

    We appreciate your cooperation and patience during this work.

    Thank You,

    Planet Engineering

    This was just sent out:

    Greetings,

    We apologize for the short notice, but it is necessary to perform some work on DSR2-2.DLLSTX4 prior to the migration scheduled for Sunday evening. During the work, DSR2-2.DLLSTX4 will be offline, however all traffic should re-route through DSR2-1.DLLSTX4 during the downtime. The work will begin at 11:59PM CST (GMT -0600) and will take about 15 minutes to complete. Once the router is reloaded, normal service should be restored before 12:30am. It is possible that customers will experience some packet loss and higher than normal latency while the work is being done.

    Thank you for your patience,

    Planet Engineering
