Extended maintenance sessions in October.

Maintenance work on Shaheen II is taking longer than originally envisioned. Service will not be returned by tomorrow but we are hopeful that Shaheen II will be operational by the end of the week. There will be occasional disruption to the CDLs, but at least one CDL will be available for users to login to during this period.
