Service Alerts

Update: 10/5/2015, 12:15pm - Things have stablized for the Zimbra service including ZWC. We suspect that there were network problems for one group of users that resulted in looping of bad requests to connect that started eating up resources for everyone. We are still investigating.

10/5/2015, 11:30am - We are seeing intermittent problems connecting to the Zimbra Webmail Client. Some users have been able to connect using ZWC after multiple attempts and we are hearing that users are not experiencing problems using an SMTP client like Thunderbird. We are looking for the root cause of this degradation in service and will send updates as we have them.

ISC Networking and Telecommunications Email Service - Security Tips

From the ISC Information & Security Office:

While Penn may be closed for the winter break, most of us will continue to use our computers for business and pleasure. Don't let the holiday rush allow you to drop your guard. Below are 7 simple tips to help you identify and avoid phishing scams and to work securely off-campus during the Break.


  • No organization at Penn will ever ask you for your username and password via e-mail.
  • Double-check the URL of any websites you are being told to click on in e-mail messages, especially if once directed there, you are asked to login. Be suspicious if the message claims to be from Penn, but the URL goes to a .com, .org, .net, etc. address.
  • If you believe you have mistakenly clicked on a link or otherwise disclosed private information in a phishing attack, immediately change your e-mail and PennKey passwords.

Working Remotely:

  • Make sure you are working on a computer that has software with up-to-date security patches, the firewall setting turned on, and antivirus software installed.
  • Use a dedicated computer that no one else uses. If that's not possible, use Remote Desktop to reach your campus computer.
  • Don't use unsecured wireless hot spots at hotels, airports, coffee shops or other public areas.
  • Be especially careful about what data you store on portable devices, since they are more easily lost and stolen. Consider encryption or remote file deletion.
