LAX and San Jose MCU's which serve the west coast are being retired. As part of platform improvements, the west coast will be served by a new MCU in Oregon that is going online today.
The reasons for this are that the new provider in Oregon will be providing a larger, more reliable machine with a higher bandwidth tier tied to it. After investigating this, aggregating the west of the US to a single central MCU in Oregon appears to be the way to go, at least for now.
Also keep in mind that a WebMeeting information channel to better inform partners and users about information like this is something that we as 3CX are considering.
