I'm one of those with the System.IndexOutOfRangeException problem. A while back I found it was helpful to use the stack trace produced by this error to tell me when the server software has been updated, that is, when a bug fix or new/changed functionality has been rolled out.
I believe my crude indicator changed since yesterday, so I wouldn't read too much into the connection timeout issue this a.m., just go about your business verifying if any bug(s) or typo(s) you had reported have been addressed with this latest release.
