We’ll be completing the final phase in our big infrastructure upgrade we mentioned a few weeks back this Sunday night morning.

Because of this, you won’t be able to access your Campaign Monitor account for roughly six hours between 12.30am and 6.30am on Sunday morning US EST (convert this to your own time zone). We’ve gone very conservative with this window and are hoping to have this upgrade completed sooner.

And don’t worry, the application will continue to tick along nicely behind the scenes adding new subscribers and tracking your campaigns, you just won’t be able to log in to the Campaign Monitor interface.

New IP Range

Our system upgrade also means we’ll be delivering your campaigns from a new set of IP addresses. In our continued commitment to getting your email delivered, we’ve been submitting these new IP’s to the big ISP’s like AOL, Hotmail and Yahoo! and many others to ensure we continue to be whitelisted. Our new IP range is:

72.15.222.60 - 72.15.222.74 (inclusive)

Also, anyone who has whitelisted our old IP’s for their own server or corporate network or set up SPF/Sender ID records should update their mail servers and DNS accordingly. We’ll make an announcement here as soon as the upgrade is completed.

Update: Please note that we’ve changed the maintenance times from Sunday night to very early Sunday morning starting at 12.30am. By the time most of you guys are out of bed, we’ll be good to go.

Final update: DONE! Our infrastructure upgrade is now complete and we’re purring along nicely in our new data center. We’ve been doing some serious testing for the last few hours, but if you spot anything that looks out of the ordinary, don’t hesitate to drop us a line. Some subscriber list RSS feeds might not work for the next few hours until re-delegation is completed.

Thanks for your patience, we’ve had a long day and it’s well past beer o’clock at the Freshview office!
