Udpate to Ongoing Slowness on Online Course Websites
August 18, 5:15pm Update:
The IS team strongly believes that the problem you currently experience when accessing online courses lies in the core storage network that is used by nearly every server here at the School. That's why there have been slowdowns in email, My Documents, and a number of other services. The database for the online courses is affected by this problem as well.
At or just before 8pm tonight, the IS team will find out if they can do a quick patch to the core storage network which should resolve the problem, or if they have to take down all the servers in the data center, apply the patch, and bring everything back up. If it's the latter scenario, there will be no access to email, CoursePlus, the online courses, the my.jhsph.edu portal, or anything else from about 8pm until 4am tomorrow (Friday) morning.
The original part of this post is below.
Yesterday's power outage at the School has led to ongoing problems with various systems at the School. The database cluster that powers online courses is responding very slowly to requests. Requests that took a fraction of a second before the power outage are now taking 20-25 seconds to complete. This is resulting in General slowness and timeout errors across all of the courses.
Information Systems is aware of the problem and spent most of the night working on resolving it. We still do not have a timeline for when the problem will be fixed. We hope that will hapen today.
In the meantime, if a page is taking a while to load, simply let it run its course. Clicking multiple times will not make the page load faster.
We thank you for your patience and apologize for the inconveniences this has caused.
