The National Audit Office says the government's roll out of superfast broadband to 90% of the population is running late.
More than 80% of Norfolk's homes and businesses are set to be able to access superfast broadband services by June 2015.
Today, a major conference is being held in Bury St Edmunds in Suffolk, to call for faster broadband connection speeds.
A new superfast broadband programme that's being rolled out in Suffolk was officially launched today.
It's going to mean hundreds more jobs and the prospect of £2 billion going into the local economy.
Among the first to benefit are people in Lowestoft - from where our correspondent Malcolm Robertson reports
A scheme to bring super-fast broadband to every home and business across Suffolk is already three months ahead of schedule.
The county council and BT will celebrate the arrival of high speed internet to communities in Lowestoft today, 6 August.
It's the first of 16 across Suffolk which, by the end of September, will have access to speeds of at least two mega-bits-per-second.
By the end of 2015, every home and business in Suffolk will have access to the technology.
There has been a warning that thousands of internet users in the region won't get the broadband speed they've been promised.
The National Audit Office has picked out Suffolk and Norfolk as two of only four counties that won't reach Government targets of 90% of people getting super-fast internet connection by 2015.
That date has already slipped by nearly two years although Suffolk County Council says it is on target to deliver 85% superfast broadband.
The report comes on the day that Croxton near Thetford became the first village in the country to get a new fibre-optic service as part of the national broadband delivery scheme.

Suffolk County Council says it's on target to have superfast broadband in 85% of homes in the county in two years.
A report by the National Audit Office said Suffolk was one of four areas in the country that would fail to meet a government target of 90% having high-speed internet access.
Suffolk says more than 8,000 properties would have better broadband by Christmas 2013.
The rest of the programme would be delivered by 2015 with every household having access to at least 2 MegaBits per second download speed.
Mark Bee, Leader of Suffolk County Council, said: "We consulted with residents and businesses about the kind of broadband service they wanted. They told us that they would rather we rolled out superfast broadband to 85% of the population with the remaining 15% receiving an improved broadband speed."
A government target of getting superfast broadband into 90% of homes by 2015 is running two years behind schedule.
The high-speed internet access would be 24 Megabits per second or higher.
There was a wide-range of government funding allocations in the Anglia region which were based of a finance model of broadband need:
- £15.4 million for Norfolk
- £14.3 million for Lincolnshire
- £11.7 million for Suffolk
- £6.8 million for Cambridgeshire and Peterborough
- £6.5 million for Essex
- £4.2 million for Buckinghamshire and Hertfordshire
- £4.1 million for Northamptonshire
- £2.0 million for Bedfordshire and Milton Keynes
Norfolk and Suffolk are among only four areas of the UK that are currently projected to fail to meet a government target on high-speed broadband roll-out.
The government has set a target of 90% of homes connected to superfast computer networks by March 2017.
The National Audit Office says Norfolk and Suffolk won't meet that target and more funding may be needed in the two counties.
So far £15.4 million has been allocated in Norfolk and £11.7 million in Suffolk.
Four villages near Cambridge are among the first in South Cambridgeshire to be considered for the roll-out of superfast broadband.
Elsworth, Graveley, Papworth and Willingham are among the first that could be included in the first tranche of broadband across the county.
Business and residents are being reassured that many other South Cambridgeshire areas will be reached by subsequent phases of the roll-out in 2014, with every community being reached by the end of 2015.
Cllr Nick Wright, South Cambridgeshire District Council’s lead member for economic development, said: “We understand that people may be disappointed that only a few of our villages are being considered for the first phase.
“We’re one of the fastest growing areas in the country, and our businesses are crying out for up to date technology infrastructure, which is why we’re working with the Connecting Cambridgeshire programme to bid for extra Government funding to get the best possible outcome for our district.”
A group of residents living in Uppingham near Corby were so fed up with their slow broadband they decided to take matters into their own hands.
They all clubbed together to get the latest fibre optic technology installed.
Nwo the village has among the best broadband speeds in the country.
Britain faces a broadband "postcode lottery" with dramatic variations in speed within cities and towns, despite the increasing availability of 4G, a new study suggests.
In the worst case - Birmingham - there is a difference of up to 89% between the fastest and slowest broadband, the report found. Northampton was the fourth worst with a 78% difference between fast and slow according to uSwitch.com.
