5:45 PM -- Right now is probably the wrong time for a company to vanish from the Web.

For the past couple of days, the CyOptics Inc. Website has been unresponsive, behaving as if -- well, as if it were killed off.

Ali Abouzari, VP of marketing, returned a Light Reading call today to say that everything's fine, and that he'd been on the road and unaware of the site being down. It's being worked on, as IT types say.

Separately, though, a reader points out that Pirelli SpA (Milan: PECI.MI) wants to sell its 34.5 percent stake in CyOptics -- one of a few telecom investments Pirelli is trimming, it appears. Pirelli invested $20 million in CyOptics in 2008, as the companies paired up to work on integrated photonics. (See Pirelli, CyOptics Team.) We'll try to get a status report on that alliance.
