We are currently in the process of upgrading our SSL certificates to use the SHA-2 algorithm instead of SHA-1. This should be a routine upgrade, but if anyone notices anything funky, please do let us know!
We have rolled the new certificate out to about half our relays, for
.pagekite.me names only. If everything looks good, the certificate will be rolled out to the entire fleet and all PageKite supplied TLDs on the weekend.
There is one known downside to this - it breaks compatibility with some obsolete versions of Windows. The support for these was already marginal, and we don't feel we can compromise on security for legacy systems forever. Hopefully this won't cause too much bother for anyone.
Also - Happy Thanksgiving, USA!
