Just received another PayPal email warning of some possible outages during the fall/winter holiday season. Text from them below.
We’ve let you know many times over the past few months that we have been making upgrades to our system to help improve the performance and availability of our services. We have scheduled a few more activities which will help make our services more scalable and ensure that they’re continuously available to our growing customer base, particularly as we near the holiday shopping season.
Please be sure to share this notification with your technical resources because network configuration changes may be necessary to avoid a disruption in service. Please note that there is also information regarding a short service interruption for Payflow on October 1st.
