State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,

prescribed time period.

FASTNET Corporation (the "Company") could not complete the filing of its Annual
Report on Form 10-K for the fiscal year ended December 31, 2002 ("Annual
Report") due to delay in compiling and analyzing information related to the
Company's Estimated impairment loss in accordance with FAS 142, "Goodwill and
Other Intangible Assets," disclosures required to be included in the Annual
Report, which delay could not be eliminated by the Company without unreasonable
effort and expense. In accordance with Rule 12b-25 of the Securities and
Exchange Act of 1934, as amended, the Company will file the Annual Report no
later than the fifteenth calendar day following the prescribed due date.

the fiscal year ended December 31, 2002. The Company expects, however, to report
a net loss of $18,099,688 for the year ended December 31, 2002 compared to a net
loss of $8,929,568 for the year ended December 31, 2001. The Company also
expects to report a working capital deficit of $15,606,257 million for the year
ended December 31, 2002. The Company's independent auditors have indicated they
expect to include in their report on the Company's financial statements for the
period ending December 31, 2002, an explanatory paragraph about the substantial
doubt of the Company's ability to continue as a going concern.
