Business hosting outfit DataGate has fallen off the internet today, with customers unable to raise the firm on the phone too.
The London-based firm's own website is currently unavailable, as are those of its customers.
Reg correspondents say DataGate disappeared at at about 8am.
Web developer Robin Tong this afternoon claimed on Twitter that the firm had a Level 3 routing error.
El Reg hasn't been able to reach the firm to confirm the cause of the glitch or its prognosis. Anyone at DataGate who would like to clear things up for their customers should get in touch. ®
