UK-based internet service provider (ISP) Wave Rider has been disconnected by London Network Access Point (LONAP).
According to The Register, action is thought to have been taken by the internet exchange point (IXP) last week after problems with an invoice.
However, a spokesman for Wave Rider told the site that "talks with LONAP are ongoing".
Sebastien Lahtinen, Chairman of LONAP, did not make any comment on the reasons behind the dispute with the ISP but did explain that it is as yet unresolved.
He was quoted as saying: "We haven't spoken to [Wave Rider] today. We'd like to hear from them."
Based in London, LONAP is a neutral, not-for-profit Internet Exchange Point.
Since it was founded in 1997, it has "facilitated traffic interchange", or peering, between its various members.
LONAP is currently one of the largest IXPs in the UK.
