Quantifying "reasonable" requires some context. If all the connection is used for is to let LAN users connect to fairly standard services ... e-mail, http, ftp, and such ... then catching 3-5 minute delays is probably more trouble than it is worth. (I don't have a backup connection here, for example, because we fit this model, and our interruptions are almost always that short. OTOH, we do have offsite fallbacks for MX (e-mail) and DNS.) At the other extreme, if the connection supports access to the Web site that customers use to place orders, even a few seconds of downtime can be a problem. Only you can know how long an interruption is too long for your specific situation. -- -----------------------------------------------"Never tell me the odds!"-------------- Ray Olszewski -- Han Solo Palo Alto, California, USA [EMAIL PROTECTED] ------------------------------------------------------------------------------------------- _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
