Update - 5/10/2016, 11:00am - Yesterday's situation seems more stable than even last night and we continue to see infrequent message delays of 2-3 minutes. We are still monitoring but have no new information on the cause.
Update - 5/9/2016, 7:00pm - We are not seeing an obvious root cause of the problem. Things appear stable since
servers are no longer disconnecting but we continue to see some warnings of mail
delivery slowness. We'll continue to monitor the situation.
5/9/2016, 4:40pm - We have identified a problem with the ISC managed mail routers. The servers are intermittently dropping connections. We suspect this this behavior probably results in slowness in mail delivery but are still investigating. Please be aware that a problem with the mail routers will affect Exchange, Zimbra and PennO365 email services. We will send updates as we can.
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.
For more details, see:
- 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.
