Non-ASCII characters in URLs in firefox

On coxeter we have changed the default in firefox so that URLs that have non-ASCII characters will be displayed using punycode (which only uses ASCII) to alert users to potential homograph attacks.  If you need to allow non-ASCII characters in URLs then you can type about:config in the Location Bar (sometimes called the Address Bar) to change your setting for the network.IDN_show_punycode variable to false.

coxeter and escalator updates on 2017mar29 were successful

coxeter and the escalator server appear to be working fine after the updates today.

Closing old blog/wiki sites

The old (apparently abandoned) blog and wiki sites on blog.math.toronto.edu and wiki.math.toronto.edu will be closed and completely removed from our servers. We are planning to move to a much newer blog/wiki server shortly after the end of this term and we are currently planning to restore only the undergraduate and graduate blogs and specially-requested wiki sites. Please let us know if there is a blog/wiki site that you are still using.

Updates at 4:15pm on Wednesday March 29, 2017

coxeter and the escalator server will have software updates applied tomorrow Wednesday afternoon, March 29, 2017 which will require rebooting (the servers will be unavailable starting at 4:15pm). Since some updates will be applied while the servers are still up there may be some temporary issues with some software. We hope that any such issues will be minor and by doing most of the upgrading before bringing systems down the shorter downtime will be worth the potential minor problems. Please restart any programs if you observe problems during the upgrades (and please let us know at requests@math.toronto.edu, so we can investigate). We expect the systems to be back up by 5:00pm.

Updates at 4:15pm on Wednesday March 1, 2017

The departmental servers coxeter, sphere, and the web, share, ptr, and blog/wiki servers will have software updates applied on Wednesday afternoon, March 1, 2017 which will require rebooting (most servers will be unavailable starting at 4:15pm). Since some updates will be applied while the servers are still up there may be some temporary issues with some software.

We will also be moving some network switches to a UPS (in order to handle minor power outages) so some departmental servers (such as the mail server) will temporarily not be reachable during this update time.
